I bought a few magnets and just messed around. I found that not all parts were polar exclusive. This makes me wonder if the magnetic force is the same everywhere in the magnet? In order to answer this question, it is necessary to know the isotropy. What is isotropy? That is, the variables of an object are the same no matter what direction they are measured. If it's different, it's called anisotropic. While reading the encyclopedia, I was instantly shocked. Crystals are anisotropic, do you think this is counterintuitive? This brings us to the whole and the system. That's right, the crystal as a whole is regular. However, this just means that it has a regular shape. It is true that shapes do give objects distinctive properties. For example, the ball is not easy to be stable. However, in terms of the system, or in terms of dynamics, crystals are not fluid. Because a fluid is an isotropic object. It is not known why amorphous solids are isotropic. As can be seen from the example of crystals, the internal neat arrangement is not isotropic. In this way, the magnet is anisotropic. But is that really the case? Some have speculated that magnetic monopoles may exist. Once, I broke a magnet. It stands to reason that the fractures are at the same pole. Then, it should be excluded. As a result, the two parts of the break actually fit together tightly, but did not separate for a long time. To illustrate, it is a bar magnet. And part of it is close to Antarctica. I think there must be a part of the South Pole that gives the Antarctic Fault Bar a magnetic force to attract the Arctic Fault Bar. I think a magnetic monopole should be isotropic, but it's self-repellent. How to say, the same pole excludes. Because the magnetic monopole does not have a second pole, the repulsive force cannot be released. It's like gluttony, which can only be torn to pieces. Sometimes, if you put the south pole of a bar magnet close to the south pole of a U-shaped magnet, you will find that they are not repellent. This is because the north pole of the bar U-shaped magnet is attracting the south pole of the bar magnet. Therefore, this is the result of the synthesis of magnetic forces.

Why are liquids isotropic? Because of liquidity, of course. Water is a system because of the flow. No matter how the system changes, it is itself. So, it has this property.

Isotropy is a property that an object has, while homogeneity is a property that a particle has. In fact, the idea of homogeneity comes from the congruence in mathematics. In fact, two particles can indeed be seen as congruent. Some people even think that all electrons are just images of electrons appearing at different locations and times, and that they are not real electrons. In order to explain the homogeneous phenomenon, it has been suggested that electrons are abstractions. How to understand? For example, the number 1. No matter who says it, it's naturally congruent. However, if the electron is abstract and not real. So, aren't people just unreal? So, the physics community did not accept this assumption.
