Magnetic monopole

We all know that the magnet should have two poles - the north and the south. A magnet with a single pole, or, as it is called, a monopole, it turns out, does not contradict science at all. In 1931, the outstanding physicist P. Dirac (1902-1984) mathematically proved the possibility of the existence of a magnetic monopole - a particle with a magnetic charge. That is, that "northern" and "southern" magnetic charges can exist separately. In addition, Dirac predicted the existence of an electron with a positive charge - a positron, which in nature was discovered in 1932. So far no one has discovered a magnetic monopole, it exists only on paper. Physicists have so far unsuccessfully started up in search of a magnetic monopole.

Magnetic and electrical phenomena are almost all similar except one. To create both electricity and magnetism (the latter arises when charges move), there are enough positive and negative electrical charges. But electricity has a source of its existence - an electric charge, and magnetism does not have a charge. There is an asymmetry. It was then that the genius of Dirac and proved that such an advantage of electricity before magnetism is not. Magnetic and electrical phenomena should be completely symmetrical.

How can we describe a magnetic monopole. The unit charge of the monopole is 38,5 times larger than the unit charge of the electron. The interaction of two magnetic monopoles is 4700 times stronger than the interaction of two electrons. Therefore, at the same speeds as the electron, the magnetic monopole 4700 times more ionizes the atoms of the environment. Such a large magnetic charge makes it easy to control a monopole even by weak magnetic fields, to accelerate it to gigantic energies that are inaccessible to electrons. A magnetic monopole should be very stable, it will not disappear until it collides with another, opposite in sign monopoly.

They searched for monopoles in a beam of accelerated particles in their collision with matter, in cosmic rays. It was not possible to pull them out with the help of powerful magnets from iron-bearing rocks and meteorites, where the monopoles of cosmic origin could become stuck and accumulate over millions of years. Even in the lunar soil, they were looking for a magnetic monopole, but without success.

Quite often there are sensational reports about the discovery of a mysterious magnetic monopole, but with a thorough check, they turn out to be false. About 30 years ago, Chinese scientists were sure that they had discovered a magnetic monopole. As it turned out later, they were wrong. In 1982, at Stanford University (USA), scientists using a superconducting magnet "caught" a magnetic monopole. But repeated, more accurate experiments, did not give anything. Finally, in 1985, at the University of London, with the help of sensitive sensors, it would seem that a magnetic monopole was discovered. But the confirmation of this discovery has not yet been.

What is the reason for such a long failure in the search for a magnetic monopole? Maybe he is very rare? Or is it not there they are looking for? Did Dirac make a mistake and incorrectly determine the charge of the monopoly? In that case, it turns out, are they looking for something?

And surprisingly, we still do not have it, as we have no proof of its impossibility, and it is not easier to confirm this impossibility than to find the magnetic monopole itself.
