The composition of a magnet is atoms such as iron, cobalt, nickel, etc. The internal structure of the atom is relatively special, and it has a magnetic moment itself. Magnet type: shape magnets: square magnets, tile magnets, special-shaped magnets, cylindrical magnets, ring magnets, disc magnets, magnetic rod magnets, magnetic frame magnets, attribute magnets: samarium cobalt magnets, neodymium iron boron magnets Powerful magnets), ferrite magnets, aluminum-nickel-cobalt magnets, iron-chromium-cobalt magnets, industrial magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, and more. The magnet is divided into a permanent magnet and a soft magnet. The permanent magnet is added with strong magnetism, so that the spin of the magnetic substance and the angular momentum of the electrons are aligned in a fixed direction, and the soft magnet is charged with electricity. (It is also a method of adding magnetic force) When the current is removed, the soft iron will slowly lose its magnetism.
Magnets can be divided into "permanent magnets" and "non-permanent magnets". Permanent magnets can be natural products, also called natural magnets, or they can be manufactured by man. Non-permanent magnets, such as electromagnets, are magnetic only under certain conditions.
