Wholesale of cylindrical magnets, magnet types: shape magnets: square magnets, tile magnets, special-shaped magnets, cylindrical magnets, ring magnets, disc magnets, magnetic bar magnets, magnetic frame magnets, attribute magnets: samarium cobalt magnets, NdFeB magnets (magnets), ferrite magnets, AlNiCo magnets, FeCrCo magnets, industry magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc. Magnets are divided into permanent magnets and soft magnets. Permanent magnets are added with strong magnetism, so that the spin of the magnetic substance and the angular momentum of electrons are aligned in a fixed direction, while soft magnetism is added with electricity. (It is also a method of adding magnetic force) Waiting for the current to remove the soft iron will slowly lose its magnetism.
