Is the rare earth health chain really useful?

The principle of magnetic therapy is to stimulate acupoints with bionic magnets, which has the magical effect of keeping fit, growing taller and stovepipe.

I don't know what the bionic magnet is, and I don't know what the magnet itself does to the human body. If it really works, there will be no dwarfs. This invention deserves the Nobel Prize. Simply put, a big event is just a joke.

Generally speaking, magnetotherapy has two sources of magnetic field. One is to use permanent magnetic materials, including rare earth cobalt alloy, ferrite and other natural magnetic substances; The other is to use electricity for electromagnetic rotation. Under normal circumstances, magnetic therapy products can be used without plugging in, and are generally made of permanent magnet materials. This kind of magnetic field is often weak and easy to fail in the air; The magnetic field of electro-gyromagnetic can be adjusted manually, which is widely used.

In daily life, belts, insoles and underwear that claim to have "magnetic sheets", "magnetic blocks" and "magnets" are all made of permanent magnet materials, but the magnetic field is actually very weak. Ouyang Hao bluntly said: "If consumers wear thicker clothes, permanent magnet materials will be a little farther away from the human body, and the effective magnetic field will be smaller or even negligible. The curative effect can be imagined."
