Permanent magnets are used in hard drives, motors, cars, generators, televisions, phones, headphones, speakers, transducers, sensors etc. The most common use of a magnet is the pulling force to attract other magnetic items but it has various functions in electronic tools as well. That was a very short description of, what you can use a ...
Permanent magnets are divided into two categories: 1. Metal alloy high-temperature magnets include NdFeB high-temperature magnets Nd2Fe14B, SmCo high-temperature magnets, AlNiCo high-temperature magnets. 2. Ferrite permanent magnets high-temperature magnets: its atom internal structure of the contrast No, it has a magnetic moment itself.
Alnico magnets have the benefit of having the lowest temperature coefficient, or temperature stability of all of the permanent magnet materials. Plus, they can be calibrated and have high residual induction.Before the development of rare earth magnets in the 1970's, alnico was the strongest type of permanent magnet.
