Application of magnet in traditional industry

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

For example, electrification would not be possible without magnetic materials, because generators are used to generate electricity, transformers are used to transmit electricity, motors are used in electrical machinery, and speakers are used in telephones, radios and television sets. Magnetic steel coil structure is used in many instruments. I've already talked about this in other parts of the story.
