Probably not someone who would not ever come to mind the question of what is the magnetic field.Throughout its history tried to explain ether vortices, cranky multidimensional spaces, magnetic monopoles, and many others.
We all know that the magnets are rotated to each other like poles repel and unlike ones - are attracted.This force will vary depending on the distance of the two parts are separated from each other.It turns out that describes what creates the magnetic aura around him.However, when applying the two alternating fields having the same frequency, when one is shifted in space relative to each other, the effect is obtained, which is called "the rotating magnetic field."
The value of the object being studied is determined by the force with which a magnet is attracted to another, or to hardware.Accordingly, the greater the attraction, the larger the field.Force can be measured using conventional mechanical scales: for this purpose on one side is placed a small piece of iron, and the other - the weights designed to balance the force of attraction to the magnet of the metal.
For a more precise understanding of the subject theme should explore the properties of the magnetic field:
- generated by an electric current, iemoving charges;
- found in their impact on the electric current;
- exists independently of our knowledge of it and from ourselves.
What is the magnetic field of the person?
Asked about the fact that such a magnetic field, it is necessary to say that it is in humans.At the end of 1960, due to intensive development of physics was established meter "SQUID".Its action is due to the laws of quantum phenomena.He represents a magnetometer sensor element used for the study of the magnetic field and such quantities such as electric current.
«SQUID" fairly quickly began to use to measure fields that are generated by living organisms and, of course, man.This gave impetus to the development of new fields of research based on the interpretation of information supplied by such a device.This area became known as "biomagnetism."Why
earlier in determining what magnetic field, no studies in this area?It turned out that it is very weak in organisms, and its measurement is a difficult physical challenge.This is due to the large number of magnetic noise in the surrounding area.So to answer the question about what is the magnetic field of the person, and study it without the use of special security measures is simply not possible.
around a living organism such a "halo" occurs for three main reasons.Firstly, thanks to ionic points that appear as a result of the electrical activity of cell membranes.Secondly, due to the presence of tiny ferromagnetic particles fallen accidentally or introduced into the body.Third, when external magnetic fields are applied, it turns heterogeneous susceptibility of various organs, which distorts the scope imposed.
