What is a magnet and what is its function?

Types of magnets:

Shape class magnets: square magnets, tile magnets, shaped magnets, cylindrical magnets, ring magnets, round piece magnets, magnetic bar magnets, magnetic frame magnets.

Property 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.

Applications in traditional industries:

We have already mentioned the practical applications of some magnetic materials when we talked about their magnetic origin, electromagnetic induction, and magnetic devices. In fact, magnetic materials have been widely used in various aspects of traditional industry.

For example, without magnetic materials, electrification would be impossible, because generators are used for power generation, transformers for power transmission, electric motors for electrical machinery, and loudspeakers for telephones, radios, and televisions. Numerous instruments and meters have to use magnetic steel coil structure.
