Shape magnets: square magnets, tile magnets, irregular magnets, cylindrical magnets, ring magnets, disc magnets, bar magnets, magnetic frame magnets.

Performance magnets: Sm-Co magnet, Nd magnet (strong magnet), ferrite magnet, Al-Ni-Co magnet, Fe-Cr-Co magnet.

Industry magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc.

Magnets are divided into permanent magnets and soft magnets. Permanent magnets strengthen magnetism, so that the spin of magnetic substances and the angular momentum of electrons are arranged in a fixed direction, while soft magnets are electrified. (It is also a method of magnetizing. ) Soft iron will slowly lose its magnetism after being removed by equal current.

Application in traditional industries;

When talking about magnetic sources, electromagnetic induction and magnetic devices of magnetic materials, we have mentioned some practical applications of magnetic materials. In fact, magnetic materials have been widely used in all aspects of traditional industry.

For example, electrification is impossible without magnetic materials, because power generation requires generators, power transmission requires transformers, motors require motors, and telephones, radios and televisions require speakers. Magnetic steel coil structure is used in many instruments.
