How are the processes of magnetization and demagnetization of ferromagnetic materials explained?
October 29, 2020 | Education|
The magnetization of a ferromagnet occurs in an external magnetic field. The electron spins are oriented in this magnetic field in such a way that the individual domains are displaced so that the volume of the domains oriented along the external field increases. During demagnetization, the domains are oriented chaotically. This leads to the fact that the total magnetic field of the ferromagnet decreases.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
