The application of magnetic material in the traditional industries
Only the material can be adsorbed to the magnet can play the role of separating magnetic field. And the thicker the material is, the better the magnetic effect is.
The highest performance magnets are rare earth magnets. Among the rare earth magnets, NdFeB magnets are the most powerful magnet. However, in more than 200 degrees Celsius environment, samarium cobalt is the most powerful magnet.
In telling the story of magnetic materials source, electromagnetic induction, magnetic devices, we have mentioned some practical application of magnetic materials. In fact, the magnetic material has been widely used in various aspects of the traditional industries. For example, if there is no magnetic material, electrification has become impossible. Because the power will use the generator, transformer, electric machinery transmission should use to use motor, telephone, radio and TV will use loudspeaker. Many instruments should use magnetic coil structure.
