We've mentioned the line of force before, and I think it's valuable. So, let's talk about it a little bit more. Last time, when the force field emits a line of force, the line of force starts to scatter. As a result, the line of force meets the walnut in motion, so the line of force returns. However, the lines of force have to return to the force field, so the force is broken down. So, the question is whether the lines of force are mathematically or real-life? We know that light rays, i.e., beams, contain photons. Although the photon has zero mass at rest, it is in motion. So, it has a sporty quality. In this way, the light cannot be mathematically meaningful. And it's a real line, not something that was thought out like a magnetic line. Magnetic lines, on the other hand, are lines in the mathematical sense. So, what about the line of force? What are your opinions on this? Mizukawa said.

The length of a line in the mathematical sense is infinite, whereas the moment of action cannot be infinitely long. Therefore, the line of force must be finitely long. That is, it is three-dimensional.

Duenias, if the lines of force were really three-dimensional, what about physicists before Faraday who didn't find them? That's right, the force is limited. However, there can be infinity in finiteness. For example, there are infinite decimal places between 3 and 4. You might say that if the lines of force were one-dimensional, then the lines of force would not cross and the decomposition of the forces would not occur. Think about it, can one-dimensional lines also cross? My answer is yes. So, your consideration is unnecessary. When we talked about edge effects earlier, we beged the question: why do objects decompose differently? Do you want to be able to do it if the lines of force are three-dimensional? This is only the case when there is infinity. Isn't there a greater number of one-dimensional lines than three-dimensional lines? If there is not enough coverage, can the line of force meet other objects? In fact, the most important thing is that if the line of force is three-dimensional, then the shape of the object has fractals. Of course, every object has fractals. However, these lines of force are groups of fractals that cannot be ignored. Due to their large number, they inevitably affect the mechanical properties of the object. If so, it is impossible for an object to be without a distinctive property. However, physicists did not find out. This means that the lines of force are not three-dimensional.

Liuzifeng said it well, but I have something to add. The light rays diverge centrally, while the magnetic lines diverge parallelly. So, how do the lines of force diverge? If this question is not clearly judged and analyzed, won't it fall into a misunderstanding? I used to talk about central divergence, but I thought it wasn't. I think it's parallel divergence, the kind that diverges vertically and horizontally.

Margarita, I disagree on this issue. If it is parallel divergence, how does the force of the hand get to the walnut? It is very cloudy, and the radiation range of the center divergence is wider. In addition, because the magnetic inductance lines of the magnetic field of the magnet are parallel and divergent, the degree of magnetization of the object in the magnetic field is not high.

Mizukawa rice, some things are not what they seem.

Perhaps! Recently, I have been looking at Lady's biography, which has a detailed description of the line of force. I thought you could check it out. Faraday, as a famous electromagnetist, is worth learning from.

Margarita said: I have been reading it for a long time, and the book is wonderful.
