At present, the theoretical basis of electromagnetic action in theoretical physics is Maxwell's electromagnetic transformation theory. This theory can be expressed as follows: any time-varying electric field in space can excite magnetic field, and any time-varying magnetic field in space can also excite electric field. This is also the theoretical basis of light propagation in space at present. For the theoretical basis of Maxwell's electromagnetic transformation itself, I think he used such a physical or mathematical model: the change of one quantity causes or transforms into another quantity with different properties. I think it is imperfect and unnecessary to use such a model to establish a basic theory of physics. I have two reasons. First, it should be conditional that the change of one quantity causes or transforms into another quantity with different properties; Second, there must be a process when the change of one quantity causes or transforms into another quantity with different properties. But his electromagnetic transformation theory is unconditional and process-free, at least so far, and it is impossible to give it. Perhaps some people think that this unconditional and process-free theoretical assumption is the essential basis of electromagnetic principles, so in fact, I prefer to establish theories from a more classical physical point of view and analyze the essential processes of several existing main electromagnetic action principles. In fact, I have established a theory that I think is very good. I hereby declare that I don't think Maxwell's electromagnetic transformation theorem is completely correct or wrong, but what kind of essential degree this theory has reached for physics. The purpose of my theory is to explain the more specific essential process of electromagnetic action. I have no doubt about the correctness of Maxwell's electromagnetic theorem equations, after all, their application is so successful. This is a fairly mature theory. My theoretical function is the concretization of the electromagnetic action process, which is not contradictory to Maxwell's theory itself. But this does not mean that my theoretical and explanatory work is unnecessary and meaningless. On the contrary, its significance is very great. I think there is an essential difference between mathematics and physics. His theory can be said to be limited to mathematics, but it is still not essential to physics. The establishment of Maxwell's electromagnetic theorem is more based on mathematical and physical reality. So it is very practical. On the other hand, it has obvious defects in physics. First of all, its research method directly leads to a problem. That is to specialize the role of electromagnetic force. Not only that, from his theory, we can't see the concrete and vivid process of material action, that is, Newtonian mechanics or other more classical physical processes. Don't say that. It doesn't matter. The unified study of forces with different properties is the eternal goal of physics. These studies can't just stay at the mathematical level. It is not unreasonable for physicists to try to explain new physical phenomena and theories with the original classical theories. All physical theories should be essentially the same. This is for the development of physics itself. Maybe you think it is of little use to the development of applied physics, and that is also a wrong idea. Both the essential development of physics and the application development related to mathematics need the essential unity of physical theory. Only by finding these unifications can we get close to the physical truth. Practical physical applications will follow. Mathematics is too much to achieve this goal. To solve this problem, we must start with physics itself. Just look at the development of theoretical physics now. I think theoretical physics has simply fallen into the quagmire of relativity and quantum mechanics. There is no essential development like Newtonian mechanics. Relativity and quantum mechanics are both new theories when physicists explain new physical phenomena with old classical theories. There is no denying that they have brought progress to physics. But no matter what vitality and hope these two theoretical systems bring to physics. But what I see is that any progress in these theories is like tearing the tip of the iceberg of physical truth. This iceberg is not visible yet. Only to find another iceberg. People are always discovering new icebergs. But you will never see the true face of these icebergs. The reason is that they neglected the research and discussion on the nature of physics when establishing physical theory. The research method is too mathematical. This is a misunderstanding that modern physicists will inevitably fall into. The reason is the development of modern mathematics. Now you may be able to appreciate the importance of unifying the goals of physics theory. For these two theoretical systems, I think it shows that there are still obvious misunderstandings in the understanding of physics in physics circles. In other words, the formation and quality of these two theories is not only a matter of the current development of physics. It should also be a man-made misunderstanding. Here I talked about the research goal of physics theory and the fundamental method of starting. So far, the purpose is to explain the necessity and significance of my theory and interpretation work. Let's go on with my theory itself.

First of all, my theory is actually based on the theory of electromagnetic propagation of light. I think the propagation of light wave energy in space depends on the medium. And this kind of substance that fills most of the universe (not necessarily the whole universe) is ether, including nuclei, electrons, neutrons and protons, all in such an environment. In fact, the name and existence hypothesis of etheric substances have long been put forward abroad. But it was later denied because of the negative results of Michelson-Morey and other experiments. Coupled with the development and successful application of Maxwell's electromagnetic theory, theoretical physics seems to have completely abandoned this assumption. No matter how absurd it seems that I put forward such a hypothesis again now, I still established my theory and used it to explain and analyze several main principles of electromagnetic action. Judging from the results, I think this theory is very promising. Relevant discussions have proved the correctness of the theory itself. I think it also reveals something quite important, which can bring great progress to physics. The following is a formal introduction to the core content of my theory. Electrons move around the nucleus in space, leaving an etheric movement pattern along its trajectory in its etheric environment. This motion form is actually formed by the circular motion of the electron acting on the ether, and this motion form of the ether can in turn act on the electron to gain a certain momentum. The arrow direction of the small circle I use is shown in figure 1. I call this small circle the flow circle. This is the essence of magnetism.
