Not long ago, I saw a northerner named Zhou Bo in qq. When he was doing experiments with electric spark, he found that electric spark bombarded special metals and produced magnetic monopoles.
Using the attraction and repulsion between the magnet and the generated magnetic monopole, it can be judged that it is a magnetic monopole, but its life span is very short and it disappears in a few hours. The magnetic field produced by his arc discharge method is very weak, magnetic, monopole and has a short life. So is there a magnetic monopole in nature? Let's look at the earth's magnetic field where we live. The earth is made up of two triangular magnets embedded together. The tip of the southern triangular magnet leaks on the triangular surface of the northern triangle to form the north pole N, and the northern triangular magnet is inserted into the southern triangular surface to leak out to form the S,
Perhaps because the magnetic field on the earth is NS, there will be no other naturally generated magnetic field on the earth, so the single-stage life of the magnetic field generated by arc will not be very long. That's because the environment will cancel the magnetic field of the magnetic monopole. The earth's magnetic field is very weak, about 0.0 1-0.02T, but the total energy of the earth's magnetic field is still huge, which can be lower than the erosion of the solar wind emitted by the sun at all times, protecting the life safety of the earth.
However, in the production of artificial magnetic materials, the remanence of modern Nd: Fe shed materials for artificial magnets is very strong, which is hundreds of times as high as the earth's magnetic field intensity, and can reach 1.8T Tesla. Modern physics experiments can create tens of Tesla intensity for creating a special magnetic field environment, but although human beings can achieve such a strong magnetic field intensity, they cannot achieve magnetic monopole. Because the magnetic field must have two magnetic poles on the same magnetic material at the same time, and the magnetic field also has holographic properties, that is, someone once wanted to get a magnetic monopole. He wanted to break one end of the N pole of a long magnet, and the rest would be the S pole, so the other end would be the magnetic monopole N, but in fact, no matter how many segments you break, the magnet still shows the existence of NS. This phenomenon is holographic, that is, magnets have memory properties. The magnetic field is always evenly distributed on the magnetic materials N and S, so it is impossible to get a magnetic monopole. But if a piece of magnetic material NdFeB is magnetized in a single magnetic field at N pole or S terminal, will it get a magnetic monopole? The answer is still no, why? The reason is the holographic nature of the magnet. Although the magnetized material is magnetized at one end of the magnetic monopole, another magnetic pole will still be found, so that the magnetized magnet is still in NS arrangement. I have also thought about whether a magnetic monopole can be obtained if a ball of magnetic material is magnetized in all directions at the same time through one end of the magnetic monopole coil. If the external magnetic field is closely distributed, if one end S of N coils used for external use is magnetized in all directions, the other magnetic pole will be inside the magnetic sphere and N will be formed in the external S, then the magnetic sphere can present a magnetic monopole to the outside? This is just an idea, and whether it can be realized remains to be tested. The above conclusion is that the magnetic field will never exist in the form of magnetic monopole, at least not in the earth environment. Even if the magnetic monopole is artificially manufactured by a special method, it is a flash in the pan, and its life will not exceed a few days, because the magnetic monopole is not allowed to exist in the big environment. In industrial magnetization, there is also an intermediate magnetic field called radiation magnetization. The most basic technology of radiating magnetic field is to magnetize the magnetized magnetic material between two coils with the same pole S or the same pole N. As a result, three magnetic fields, NSN or SNS, will be formed on the magnetized magnet, which is only the result of simple industrial tests. If further testing, it will be found that the magnetized magnet is actually NSSN or SNNS, and the two magnetic fields in the middle are 90 degrees perpendicular to both ends. This is because the magnetic field in the middle is generated externally by the same polarity of the two coils. They are two quantities. Because the holographic nature of the magnetic field determines that they have their own memory properties, we can't see any clues from the appearance alone. After in-depth study, we will understand that, for example, in our solar system, the three stars, including the sun, are all NSSN's magnetic field arrangement. They are all a combination of upper and lower vortex magnetic fields, and even the magnetic field in the center of our universe is an arrangement of NSSN.
Our universe is produced because of the magnetic field, the essential substance that supports the whole universe.
