The composition of strong neodymium magnets is iron, cobalt, nickel and other atoms, the internal structure of atoms is relatively special, and it has a magnetic moment. Magnets generate magnetic fields and have properties that attract ferromagnetic materials such as iron, nickel, cobalt, and other metals.

　　The matter is mostly composed of molecules, molecules are composed of atoms, and atoms are composed of nuclei and electrons. Inside an atom, electrons are constantly spinning and revolving around the nucleus. Both of these movements of electrons create magnetism. In most substances, however, the electrons move in different directions and are disordered, and the magnetic effects cancel each other out. Therefore, most substances do not exhibit magnetic properties under normal conditions.

　　Magnet is not invented by man, it is natural magnetite. The ancient Greeks and Chinese discovered a naturally magnetized stone called "magnetite" in nature. Stones can magically pick up small pieces of iron and always point in the same direction when swung at will.

　　After thousands of years of development, today's magnets have become powerful materials in our lives. By synthesizing alloys of different materials, the same effect as magnetite can be achieved, but the magnetic force can also be improved.

　　The earth itself has a strong magnetic field, so people themselves have an adaptation or even dependence on the magnetic field. Weak and stable magnetic fields are beneficial to the body, and magnetic therapy is often used in medical treatment. Electromagnetic waves, on the other hand, are high-energy waves whose frequencies can adversely affect the body. Therefore, magnets are harmless to the human body.
