    Magnetic field, its properties and characteristics.

A magnetic field- the form of existence of matter surrounding moving electric charges (conductors with current, permanent magnets).

This name is due to the fact that, as the Danish physicist Hans Oersted discovered in 1820, it has an orienting effect on the magnetic needle. Oersted's experiment: a magnetic needle was placed under a wire with current, rotating on a needle. When the current was turned on, it was installed perpendicular to the wire; when changing the direction of the current, it turned in the opposite direction.

The main properties of the magnetic field:

    generated by moving electric charges, conductors with current, permanent magnets and an alternating electric field;

    acts with force on moving electric charges, conductors with current, magnetized bodies;

    an alternating magnetic field generates an alternating electric field.

It follows from Oersted's experience that the magnetic field is directional and must have a vector force characteristic. It is designated and called magnetic induction.

The magnetic field is depicted graphically using magnetic lines of force or lines of magnetic induction. magnetic force lines are called lines along which iron filings or axes of small magnetic arrows are located in a magnetic field. At each point of such a line, the vector is directed tangentially.

The lines of magnetic induction are always closed, which indicates the absence of magnetic charges in nature and the vortex nature of the magnetic field.

Conventionally, they leave the north pole of the magnet and enter the south. The density of the lines is chosen so that the number of lines per unit area perpendicular to the magnetic field is proportional to the magnitude of the magnetic induction.

H

Magnetic solenoid with current

The direction of the lines is determined by the rule of the right screw. Solenoid - a coil with current, the turns of which are located close to each other, and the diameter of the turn is much less than the length of the coil.

The magnetic field inside the solenoid is uniform. A magnetic field is called homogeneous if the vector is constant at any point.

The magnetic field of a solenoid is similar to the magnetic field of a bar magnet.

FROM

The olenoid with current is an electromagnet.

Experience shows that for a magnetic field, as well as for an electric field, superposition principle: the induction of the magnetic field created by several currents or moving charges is equal to the vector sum of the inductions of the magnetic fields created by each current or charge:

The vector is entered in one of 3 ways:

a) from Ampère's law;

b) by the action of a magnetic field on a loop with current;

c) from the expression for the Lorentz force.

BUT mper experimentally established that the force with which the magnetic field acts on the element of the conductor with current I, located in a magnetic field, is directly proportional to the force

current I and the vector product of the length element and the magnetic induction:

- Ampère's law

H
the direction of the vector can be found according to the general rules of the vector product, from which follows the rule of the left hand: if the palm of the left hand is positioned so that the magnetic lines of force enter it, and 4 outstretched fingers are directed along the current, then the bent thumb will show the direction of the force.

The force acting on a wire of finite length can be found by integrating over the entire length.

For I = const, B=const, F = BIlsin

If  =90 0 , F = BIl

Magnetic field induction- a vector physical quantity numerically equal to the force acting in a uniform magnetic field on a conductor of unit length with unit current, located perpendicular to the magnetic field lines.

1Tl is the induction of a homogeneous magnetic field, in which a 1N force acts on a conductor 1m long with a current of 1A, located perpendicular to the magnetic field lines.

So far, we have considered macrocurrents flowing in conductors. However, according to Ampere's assumption, in any body there are microscopic currents due to the movement of electrons in atoms. These microscopic molecular currents create their own magnetic field and can turn in the fields of macrocurrents, creating an additional magnetic field in the body. The vector characterizes the resulting magnetic field created by all macro- and microcurrents, i.e. for the same macrocurrent, the vector in different media has different values.

The magnetic field of macrocurrents is described by the magnetic intensity vector .

For a homogeneous isotropic medium

,

 0 \u003d 410 -7 H / m - magnetic constant,  0 \u003d 410 -7 N / A 2,

 - magnetic permeability of the medium, showing how many times the magnetic field of macrocurrents changes due to the field of microcurrents of the medium.

    magnetic flux. Gauss' theorem for magnetic flux.

vector flow(magnetic flux) through the pad dS is called a scalar value equal to

where is the projection onto the direction of the normal to the site;

 - angle between vectors and .

directional surface element,

The vector flux is an algebraic quantity,

if - when leaving the surface;

if - at the entrance to the surface.

The flux of the magnetic induction vector through an arbitrary surface S is equal to

For a uniform magnetic field =const,


1 Wb - magnetic flux passing through a flat surface of 1 m 2 located perpendicular to a uniform magnetic field, the induction of which is equal to 1 T.

The magnetic flux through the surface S is numerically equal to the number of magnetic lines of force crossing the given surface.

Since the lines of magnetic induction are always closed, for a closed surface the number of lines entering the surface (Ф 0), therefore, the total flux of magnetic induction through a closed surface is zero.

- Gauss theorem: the flux of the magnetic induction vector through any closed surface is zero.

This theorem is a mathematical expression of the fact that in nature there are no magnetic charges on which the lines of magnetic induction would begin or end.

    Biot-Savart-Laplace law and its application to the calculation of magnetic fields.

The magnetic field of direct currents of various shapes was studied in detail by fr. scientists Biot and Savart. They found that in all cases the magnetic induction at an arbitrary point is proportional to the strength of the current, depends on the shape, dimensions of the conductor, the location of this point in relation to the conductor and on the medium.

The results of these experiments were summarized by fr. mathematician Laplace, who took into account the vector nature of magnetic induction and hypothesized that the induction at each point is, according to the principle of superposition, the vector sum of the inductions of the elementary magnetic fields created by each section of this conductor.

Laplace in 1820 formulated a law, which was called the Biot-Savart-Laplace law: each element of a conductor with current creates a magnetic field, the induction vector of which at some arbitrary point K is determined by the formula:

- Biot-Savart-Laplace law.

It follows from the Biot-Sovar-Laplace law that the direction of the vector coincides with the direction of the cross product. The same direction is given by the rule of the right screw (gimlet).

Given that ,

Conductor element co-directional with current;

Radius vector connecting with point K;

The Biot-Savart-Laplace law is of practical importance, because allows you to find at a given point in space the induction of the magnetic field of the current flowing through the conductor of finite size and arbitrary shape.

For an arbitrary current, such a calculation is a complex mathematical problem. However, if the current distribution has a certain symmetry, then the application of the superposition principle together with the Biot-Savart-Laplace law makes it possible to calculate specific magnetic fields relatively simply.

Let's look at some examples.

A. Magnetic field of a rectilinear conductor with current.

    for a conductor of finite length:

    for a conductor of infinite length:  1 = 0,  2 = 

B. Magnetic field at the center of the circular current:

=90 0 , sin=1,

Oersted in 1820 experimentally found that the circulation in a closed circuit surrounding a system of macrocurrents is proportional to the algebraic sum of these currents. The coefficient of proportionality depends on the choice of the system of units and in SI is equal to 1.

C
the circulation of a vector is called a closed-loop integral.

This formula is called circulation theorem or total current law:

the circulation of the magnetic field strength vector along an arbitrary closed circuit is equal to the algebraic sum of the macrocurrents (or total current) covered by this circuit. his characteristics In the space surrounding currents and permanent magnets, there is a force field called magnetic.

    • Probably, there is no person who at least once did not think of the question of what a magnetic field is. Throughout history, they tried to explain it with ethereal whirlwinds, quirks, magnetic monopolies, and many others.

    We all know that magnets with like poles facing each other repel each other, and opposite magnets attract. This power will

    Vary depending on how far the two parts are from each other. It turns out that the described object creates a magnetic halo around itself. At the same time, when two alternating fields having the same frequency are superimposed, when one is shifted in space relative to the other, an effect is obtained that is commonly called a "rotating magnetic field".

    The size of the object under study is determined by the force with which the magnet is attracted to another or to iron. Accordingly, the greater the attraction, the greater the field. The force can be measured using the usual one, a small piece of iron is placed on one side, and weights are placed on the other, designed to balance the metal to the magnet.

    For a more accurate understanding of the subject of the topic, you should study the fields:


    Answering the question of what a magnetic field is, it is worth saying that a person also has it. At the end of 1960, thanks to the intensive development of physics, the SQUID measuring device was created. Its action is explained by the laws of quantum phenomena. It is a sensitive element of magnetometers used to study the magnetic field and such

    values, such as

    "SQUID" quickly began to be used to measure the fields that are generated by living organisms and, of course, by humans. This gave impetus to the development of new areas of research based on the interpretation of the information provided by such an instrument. This direction is called "biomagnetism".

    Why, earlier, when determining what a magnetic field is, no research was carried out in this area? It turned out that it is very weak in organisms, and its measurement is a difficult physical task. This is due to the presence of a huge amount of magnetic noise in the surrounding space. Therefore, it is simply not possible to answer the question of what a human magnetic field is and to study it without the use of specialized protection measures.

    Around a living organism, such a "halo" occurs for three main reasons. Firstly, due to ionic dots that appear as a result of the electrical activity of cell membranes. Secondly, due to the presence of ferrimagnetic tiny particles that got accidentally or introduced into the body. Thirdly, when external magnetic fields are superimposed, there is a non-uniform susceptibility of various organs, which distorts the superimposed spheres.

    A magnetic field

    If two parallel conductors are connected to a current source so that an electric current passes through them, then, depending on the direction of the current in them, the conductors either repel or attract.

    The explanation of this phenomenon is possible from the standpoint of the appearance around the conductors of a special type of matter - a magnetic field.

    The forces with which current-carrying conductors interact are called magnetic.

    A magnetic field- this is a special kind of matter, a specific feature of which is the action on a moving electric charge, conductors with current, bodies with a magnetic moment, with a force depending on the charge velocity vector, the direction of the current strength in the conductor and on the direction of the magnetic moment of the body.

    The history of magnetism goes back to ancient times, to the ancient civilizations of Asia Minor. It was on the territory of Asia Minor, in Magnesia, that a rock was found, samples of which were attracted to each other. According to the name of the area, such samples began to be called "magnets". Any magnet in the form of a rod or a horseshoe has two ends, which are called poles; it is in this place that its magnetic properties are most pronounced. If you hang a magnet on a string, one pole will always point north. The compass is based on this principle. The north-facing pole of a free-hanging magnet is called the magnet's north pole (N). The opposite pole is called the south pole (S).

    Magnetic poles interact with each other: like poles repel, and unlike poles attract. Similarly, the concept of an electric field surrounding an electric charge introduces the concept of a magnetic field around a magnet.

    In 1820, Oersted (1777-1851) discovered that a magnetic needle located next to an electrical conductor deviates when current flows through the conductor, that is, a magnetic field is created around the current-carrying conductor. If we take a frame with current, then the external magnetic field interacts with the magnetic field of the frame and has an orienting effect on it, i.e., there is a position of the frame at which the external magnetic field has a maximum rotating effect on it, and there is a position when the torque force is zero.

    The magnetic field at any point can be characterized by the vector B, which is called magnetic induction vector or magnetic induction at the point.

    Magnetic induction B is a vector physical quantity, which is a force characteristic of the magnetic field at a point. It is equal to the ratio of the maximum mechanical moment of forces acting on a loop with current placed in a uniform field to the product of the current strength in the loop and its area:

    The direction of the magnetic induction vector B is taken to be the direction of the positive normal to the frame, which is related to the current in the frame by the rule of the right screw, with a mechanical moment equal to zero.

    In the same way as the lines of electric field strength are depicted, the lines of magnetic field induction are depicted. The line of induction of the magnetic field is an imaginary line, the tangent to which coincides with the direction B at the point.

    The directions of the magnetic field at a given point can also be defined as the direction that indicates

    the north pole of the compass needle placed at that point. It is believed that the lines of induction of the magnetic field are directed from the north pole to the south.

    The direction of the lines of magnetic induction of the magnetic field created by an electric current that flows through a straight conductor is determined by the rule of a gimlet or a right screw. The direction of rotation of the screw head is taken as the direction of the lines of magnetic induction, which would ensure its translational movement in the direction of the electric current (Fig. 59).

    where n 01 = 4 Pi 10 -7 V s / (A m). - magnetic constant, R - distance, I - current strength in the conductor.

    Unlike electrostatic field lines, which start at a positive charge and end at a negative one, magnetic field lines are always closed. No magnetic charge similar to electric charge was found.

    One tesla (1 T) is taken as a unit of induction - the induction of such a uniform magnetic field in which a maximum torque of 1 N m acts on a frame with an area of ​​1 m 2, through which a current of 1 A flows.

    The induction of a magnetic field can also be determined by the force acting on a current-carrying conductor in a magnetic field.

    A conductor with current placed in a magnetic field is subjected to the Ampère force, the value of which is determined by the following expression:

    where I is the current strength in the conductor, l- the length of the conductor, B is the modulus of the magnetic induction vector, and is the angle between the vector and the direction of the current.

    The direction of the Ampere force can be determined by the rule of the left hand: the palm of the left hand is positioned so that the lines of magnetic induction enter the palm, four fingers are placed in the direction of the current in the conductor, then the bent thumb shows the direction of the Ampere force.

    Considering that I = q 0 nSv and substituting this expression into (3.21), we obtain F = q 0 nSh/B sin a. The number of particles (N) in a given volume of the conductor is N = nSl, then F = q 0 NvB sin a.

    Let us determine the force acting from the side of the magnetic field on a separate charged particle moving in a magnetic field:

    This force is called the Lorentz force (1853-1928). The direction of the Lorentz force can be determined by the rule of the left hand: the palm of the left hand is positioned so that the lines of magnetic induction enter the palm, four fingers show the direction of movement of the positive charge, the thumb bent shows the direction of the Lorentz force.

    The force of interaction between two parallel conductors, through which currents I 1 and I 2 flow, is equal to:

    where l- the part of a conductor that is in a magnetic field. If the currents are in the same direction, then the conductors are attracted (Fig. 60), if the opposite direction, they are repelled. The forces acting on each conductor are equal in magnitude, opposite in direction. Formula (3.22) is the main one for determining the unit of current strength 1 ampere (1 A).

    The magnetic properties of a substance are characterized by a scalar physical quantity - magnetic permeability, which shows how many times the induction B of a magnetic field in a substance that completely fills the field differs in absolute value from the induction B 0 of a magnetic field in vacuum:

    According to their magnetic properties, all substances are divided into diamagnetic, paramagnetic And ferromagnetic.

    Consider the nature of the magnetic properties of substances.

    Electrons in the shell of atoms of matter move in different orbits. For simplicity, we consider these orbits to be circular, and each electron revolving around the atomic nucleus can be considered as a circular electric current. Each electron, like a circular current, creates a magnetic field, which we will call orbital. In addition, an electron in an atom has its own magnetic field, called the spin field.

    If, when introduced into an external magnetic field with induction B 0, induction B is created inside the substance< В 0 , то такие вещества называются диамагнитными (n< 1).

    IN diamagnetic In materials in the absence of an external magnetic field, the magnetic fields of electrons are compensated, and when they are introduced into a magnetic field, the induction of the magnetic field of an atom becomes directed against the external field. The diamagnet is pushed out of the external magnetic field.

    At paramagnetic materials, the magnetic induction of electrons in atoms is not fully compensated, and the atom as a whole turns out to be like a small permanent magnet. Usually in matter all these small magnets are oriented arbitrarily, and the total magnetic induction of all their fields is equal to zero. If you place a paramagnet in an external magnetic field, then all small magnets - atoms will turn in the external magnetic field like compass needles and the magnetic field in the substance increases ( n >= 1).

    ferromagnetic are materials that are n"1. So-called domains, macroscopic regions of spontaneous magnetization, are created in ferromagnetic materials.

    In different domains, the induction of magnetic fields has different directions (Fig. 61) and in a large crystal

    mutually compensate each other. When a ferromagnetic sample is introduced into an external magnetic field, the boundaries of individual domains are shifted so that the volume of domains oriented along the external field increases.

    With an increase in the induction of the external field B 0, the magnetic induction of the magnetized substance increases. For some values ​​of B 0, the induction stops its sharp growth. This phenomenon is called magnetic saturation.

    A characteristic feature of ferromagnetic materials is the phenomenon of hysteresis, which consists in the ambiguous dependence of the induction in the material on the induction of the external magnetic field as it changes.

    The magnetic hysteresis loop is a closed curve (cdc`d`c), expressing the dependence of the induction in the material on the amplitude of the induction of the external field with a periodic rather slow change in the latter (Fig. 62).

    The hysteresis loop is characterized by the following values ​​B s , B r , B c . B s - the maximum value of the induction of the material at B 0s ; B r - residual induction, equal to the value of the induction in the material when the induction of the external magnetic field decreases from B 0s to zero; -B c and B c - coercive force - a value equal to the induction of the external magnetic field necessary to change the induction in the material from residual to zero.

    For each ferromagnet, there is such a temperature (Curie point (J. Curie, 1859-1906), above which the ferromagnet loses its ferromagnetic properties.

    There are two ways to bring a magnetized ferromagnet into a demagnetized state: a) heat above the Curie point and cool; b) magnetize the material with an alternating magnetic field with a slowly decreasing amplitude.

    Ferromagnets with low residual induction and coercive force are called soft magnetic. They find application in devices where a ferromagnet has to be frequently remagnetized (cores of transformers, generators, etc.).

    Magnetically hard ferromagnets, which have a large coercive force, are used for the manufacture of permanent magnets.

    Let's understand together what a magnetic field is. After all, many people live in this field all their lives and do not even think about it. Time to fix it!

    A magnetic field

    A magnetic field is a special kind of matter. It manifests itself in the action on moving electric charges and bodies that have their own magnetic moment (permanent magnets).

    Important: a magnetic field does not act on stationary charges! A magnetic field is also created by moving electric charges, or by a time-varying electric field, or by the magnetic moments of electrons in atoms. That is, any wire through which current flows also becomes a magnet!

    A body that has its own magnetic field.

    A magnet has poles called north and south. The designations "northern" and "southern" are given only for convenience (as "plus" and "minus" in electricity).

    The magnetic field is represented by force magnetic lines. The lines of force are continuous and closed, and their direction always coincides with the direction of the field forces. If metal shavings are scattered around a permanent magnet, the metal particles will show a clear picture of the magnetic field lines emerging from the north and entering the south pole. Graphical characteristic of the magnetic field - lines of force.

    Magnetic field characteristics

    The main characteristics of the magnetic field are magnetic induction, magnetic flux And magnetic permeability. But let's talk about everything in order.

    Immediately, we note that all units of measurement are given in the system SI.

    Magnetic induction B - vector physical quantity, which is the main power characteristic of the magnetic field. Denoted by letter B . The unit of measurement of magnetic induction - Tesla (Tl).

    Magnetic induction indicates how strong a field is by determining the force with which it acts on a charge. This force is called Lorentz force.

    Here q - charge, v - its speed in a magnetic field, B - induction, F is the Lorentz force with which the field acts on the charge.

    F- a physical quantity equal to the product of magnetic induction by the area of ​​the contour and the cosine between the induction vector and the normal to the plane of the contour through which the flow passes. Magnetic flux is a scalar characteristic of a magnetic field.

    We can say that the magnetic flux characterizes the number of magnetic induction lines penetrating a unit area. The magnetic flux is measured in Weberach (WB).

    Magnetic permeability is the coefficient that determines the magnetic properties of the medium. One of the parameters on which the magnetic induction of the field depends is the magnetic permeability.

    Our planet has been a huge magnet for several billion years. The induction of the Earth's magnetic field varies depending on the coordinates. At the equator, it is about 3.1 times 10 to the minus fifth power of Tesla. In addition, there are magnetic anomalies, where the value and direction of the field differ significantly from neighboring areas. One of the largest magnetic anomalies on the planet - Kursk And Brazilian magnetic anomaly.

    The origin of the Earth's magnetic field is still a mystery to scientists. It is assumed that the source of the field is the liquid metal core of the Earth. The core is moving, which means that the molten iron-nickel alloy is moving, and the movement of charged particles is the electric current that generates the magnetic field. The problem is that this theory geodynamo) does not explain how the field is kept stable.

    The earth is a huge magnetic dipole. The magnetic poles do not coincide with the geographic ones, although they are in close proximity. Moreover, the Earth's magnetic poles are moving. Their displacement has been recorded since 1885. For example, over the past hundred years, the magnetic pole in the Southern Hemisphere has shifted by almost 900 kilometers and is now in the Southern Ocean. The pole of the Arctic hemisphere is moving across the Arctic Ocean towards the East Siberian magnetic anomaly, the speed of its movement (according to 2004 data) was about 60 kilometers per year. Now there is an acceleration of the movement of the poles - on average, the speed is growing by 3 kilometers per year.

    What is the significance of the Earth's magnetic field for us? First of all, the Earth's magnetic field protects the planet from cosmic rays and the solar wind. Charged particles from deep space do not fall directly to the ground, but are deflected by a giant magnet and move along its lines of force. Thus, all living things are protected from harmful radiation.

    During the history of the Earth, there have been several inversions(changes) of magnetic poles. Pole inversion is when they change places. The last time this phenomenon occurred about 800 thousand years ago, and there were more than 400 geomagnetic reversals in the history of the Earth. Some scientists believe that, given the observed acceleration of the movement of the magnetic poles, the next pole reversal should be expected in the next couple of thousand years.

    Fortunately, no reversal of poles is expected in our century. So, you can think about the pleasant and enjoy life in the good old constant field of the Earth, having considered the main properties and characteristics of the magnetic field. And so that you can do this, there are our authors, who can be entrusted with some of the educational troubles with confidence in success! and other types of work you can order at the link.

    On the Internet there are a lot of topics devoted to the study of the magnetic field. It should be noted that many of them differ from the average description that exists in school textbooks. My task is to collect and systematize all the freely available material on the magnetic field in order to focus the New Understanding of the magnetic field. The study of the magnetic field and its properties can be done using a variety of techniques. With the help of iron filings, for example, a competent analysis was carried out by Comrade Fatyanov at http://fatyf.narod.ru/Addition-list.htm

    With the help of a kinescope. I do not know the name of this person, but I know his nickname. He calls himself "The Wind". When a magnet is brought to the kinescope, a "honeycomb picture" is formed on the screen. You might think that the "grid" is a continuation of the kinescope grid. This is a method of visualizing the magnetic field.

    I began to study the magnetic field with the help of a ferrofluid. It is the magnetic fluid that maximally visualizes all the subtleties of the magnetic field of the magnet.

    From the article "what is a magnet" we found out that a magnet is fractalized, i.e. a scaled-down copy of our planet, the magnetic geometry of which is as identical as possible to a simple magnet. The planet earth, in turn, is a copy of what it was formed from - the sun. We found out that a magnet is a kind of inductive lens that focuses on its volume all the properties of the global magnet of the planet earth. There is a need to introduce new terms with which we will describe the properties of the magnetic field.

    The induction flow is the flow that originates at the poles of the planet and passes through us in a funnel geometry. The planet's north pole is the entrance to the funnel, the planet's south pole is the exit of the funnel. Some scientists call this stream the ethereal wind, saying that it is "of galactic origin." But this is not an "ethereal wind" and no matter what the ether is, it is an "induction river" that flows from pole to pole. The electricity in lightning is of the same nature as the electricity produced by the interaction of a coil and a magnet.

    The best way to understand what a magnetic field is - to see him. It is possible to think and make countless theories, but from the standpoint of understanding the physical essence of the phenomenon, it is useless. I think that everyone will agree with me, if I repeat the words, I don’t remember who, but the essence is that the best criterion is experience. Experience and more experience.

    At home, I did simple experiments, but they allowed me to understand a lot. A simple cylindrical magnet ... And he twisted it this way and that. Poured magnetic fluid on it. It costs an infection, does not move. Then I remembered that on some forum I read that two magnets squeezed by the same poles in a sealed area increase the temperature of the area, and vice versa lower it with opposite poles. If temperature is a consequence of the interaction of fields, then why shouldn't it be the cause? I heated the magnet using a "short circuit" of 12 volts and a resistor by simply leaning the heated resistor against the magnet. The magnet heated up and the magnetic fluid began to twitch at first, and then completely became mobile. The magnetic field is excited by temperature. But how is it, I asked myself, because in the primers they write that temperature weakens the magnetic properties of a magnet. And this is true, but this "weakening" of the kagba is compensated by the excitation of the magnetic field of this magnet. In other words, the magnetic force does not disappear, but is transformed into the force of excitation of this field. Excellent Everything rotates and everything spins. But why does a rotating magnetic field have just such a geometry of rotation, and not some other one? At first glance, the movement is chaotic, but if you look through a microscope, you can see that in this movement system is present. The system does not belong to the magnet in any way, but only localizes it. In other words, a magnet can be considered as an energy lens that focuses perturbations in its volume.

    The magnetic field is excited not only by an increase in temperature, but also by its decrease. I think that it would be more correct to say that the magnetic field is excited by a temperature gradient than by one of its specific signs. The fact of the matter is that there is no visible "restructuring" of the structure of the magnetic field. There is a visualization of a disturbance that passes through the region of this magnetic field. Imagine a perturbation that moves in a spiral from the north pole to the south through the entire volume of the planet. So the magnetic field of the magnet = the local part of this global flow. Do you understand? However, I'm not sure which particular thread...But the fact is that the thread. And there are not one stream, but two. The first is external, and the second is inside it and together with the first moves, but rotates in the opposite direction. The magnetic field is excited due to the temperature gradient. But we again distort the essence when we say "the magnetic field is excited." The fact is that it is already in an excited state. When we apply a temperature gradient, we distort this excitation into a state of unbalance. Those. we understand that the process of excitation is a constant process in which the magnetic field of the magnet is located. The gradient distorts the parameters of this process in such a way that we optically notice the difference between its normal excitation and the excitation caused by the gradient.

    But why is the magnetic field of a magnet stationary in a stationary state? NO, it is also mobile, but relative to moving frames of reference, for example us, it is motionless. We move in space with this perturbation of Ra and it seems to us to be moving. The temperature we apply to the magnet creates some kind of local imbalance in this focusable system. A certain instability appears in the spatial lattice, which is the honeycomb structure. After all, bees do not build their houses from scratch, but they stick around the structure of space with their building material. Thus, based on purely experimental observations, I conclude that the magnetic field of a simple magnet is a potential system of local imbalance of the lattice of space, in which, as you may have guessed, there is no place for atoms and molecules that no one has ever seen. Temperature is like an "ignition key" in this local system, includes an imbalance. At the moment, I am carefully studying the methods and means of managing this imbalance.

    What is a magnetic field and how is it different from an electromagnetic field?

    What is a torsion or energy-informational field?

    It's all one and the same, but localized by different methods.

    Current strength - there is a plus and a repulsive force,

    tension is a minus and a force of attraction,

    a short circuit, or let's say a local imbalance of the lattice - there is a resistance to this interpenetration. Or the interpenetration of father, son and holy spirit. Let's remember that the metaphor "Adam and Eve" is an old understanding of X and YG chromosomes. For the understanding of the new is a new understanding of the old. "Strength" - a whirlwind emanating from the constantly rotating Ra, leaving behind an informational weave of itself. Tension is another vortex, but inside the main vortex of Ra and moving along with it. Visually, this can be represented as a shell, the growth of which occurs in the direction of two spirals. The first is external, the second is internal. Or one inside itself and clockwise, and the second out of itself and counterclockwise. When two vortices interpenetrate each other, they form a structure, like the layers of Jupiter, which move in different directions. It remains to understand the mechanism of this interpenetration and the system that is formed.

    Approximate tasks for 2015

    1. Find methods and means of unbalancing control.

    2. Identify the materials that most affect the imbalance of the system. Find the dependence on the state of the material according to table 11 of the child.

    3. If every living being, in its essence, is the same localized imbalance, then it must be "seen". In other words, it is necessary to find a method for fixing a person in other frequency spectra.

    4. The main task is to visualize non-biological frequency spectra in which the continuous process of human creation takes place. For example, with the help of the progress tool, we analyze the frequency spectra that are not included in the biological spectrum of human feelings. But we only register them, but we cannot "realize" them. Therefore, we do not see further than our senses can comprehend. Here is my main goal for 2015. Find a technique for technical awareness of a non-biological frequency spectrum in order to see the information basis of a person. Those. in fact, his soul.

    A special kind of study is the magnetic field in motion. If we pour ferrofluid on a magnet, it will occupy the volume of the magnetic field and will be stationary. However, you need to check the experience of "Veterok" where he brought the magnet to the monitor screen. There is an assumption that the magnetic field is already in an excited state, but the volume of liquid kagba restrains it in a stationary state. But I haven't checked yet.

    The magnetic field can be generated by applying temperature to the magnet, or by placing the magnet in an induction coil. It should be noted that the liquid is excited only at a certain spatial position of the magnet inside the coil, making up a certain angle to the coil axis, which can be found empirically.

    I have done dozens of experiments with moving ferrofluid and set myself goals:

    1. Reveal the geometry of fluid motion.

    2. Identify the parameters that affect the geometry of this movement.

    3. What is the place of fluid movement in the global movement of the planet Earth.

    4. Whether the spatial position of the magnet and the geometry of movement acquired by it depend.

    5. Why "ribbons"?

    6. Why Ribbons Curl

    7. What determines the vector of twisting of the tapes

    8. Why the cones are displaced only by means of nodes, which are the vertices of the honeycomb, and only three adjacent ribbons are always twisted.

    9. Why does the displacement of the cones occur abruptly, upon reaching a certain "twist" in the nodes?

    10. Why the size of the cones is proportional to the volume and mass of the liquid poured onto the magnet

    11. Why the cone is divided into two distinct sectors.

    12. What is the place of this "separation" in terms of interaction between the poles of the planet.

    13. How the fluid motion geometry depends on the time of day, season, solar activity, experimenter's intention, pressure and additional gradients. For example, a sharp change "cold hot"

    14. Why the geometry of cones identical with Varji geometry- the special weapons of the returning gods?

    15. Are there any data in the archives of special services of 5 automatic weapons about the purpose, availability or storage of samples of this type of weapon.

    16. What do the gutted pantries of knowledge of various secret organizations say about these cones and whether the geometry of the cones is connected with the Star of David, the essence of which is the identity of the geometry of the cones. (Masons, Jews, Vaticans, and other inconsistent formations).

    17. Why there is always a leader among the cones. Those. a cone with a "crown" on top, which "organizes" the movements of 5,6,7 cones around itself.
