Magnets are one of the common goods sold in quite a few infernal stores.
Magnets
Magnets are composed of iron, cobalt, nickel and other atoms, the internal structure of its atoms is relatively special, itself has a magnetic moment. Magnets are capable of generating magnetic fields and have the property of attracting ferromagnetic substances such as iron, nickel, cobalt and other metals.
Types of magnets: shape magnets: square magnets, tile magnets, shaped magnets, cylindrical magnets, ring magnets, round sheet magnets, magnetic bar magnets, magnetic frame magnets, attribute magnets: samarium cobalt magnets, neodymium iron boron magnets (powerful magnets), ferrite magnets, alnico magnets, ferrochrome cobalt magnets, industry magnets: magnetic components, motor magnets, rubber magnets, plastic magnets and other types.
Magnets are divided into permanent magnets and soft magnets, permanent magnets are coupled with strong magnetism, so that the spin of the magnetic material and the electron angular momentum into a fixed direction of the arrangement of soft magnets is coupled with electricity. (also a method of adding magnetic force) When the current is removed, the soft iron will slowly lose its magnetism.
