What is a permanent magnet? What is the use?

Definition: Magnets that do not require magnets to maintain their magnetic field. Permanent magnets penusitelttluagtebcmaterid permanent magnets can be natural products, also known as natural magnets, or magnets can be made by hand (the strongest magnet is neodymium iron boron magnet) with wide magnetic Hysteresis loop, high coercivity, high remanence, a material that maintains a constant magnetic state upon magnetization. Also known as permanent magnet materials, hard magnetic materials. In the application, the permanent magnet operates in the second quadrant demagnetization portion of the magnetic saturation line after the deep magnetic saturation and magnetization. The permanent magnet should have the highest possible coercive force Hc, residual magnetic bromine and maximum magnetic energy product (BH) meters to ensure the storage of maximum magnetic energy and stable magnetic properties. The mainstream permanent magnets are: rare earth permanent magnet material, sintered ferrite, rubber magnetic, aluminum nickel cobalt, samarium cobalt. The strongest permanent magnet depends on your specific application environment.
