Tile Magnets Magnetization Process
First, the reversible displacement of the domain wall
When the external magnetic field is small, for the magnetic domain with the same or less external magnetic field with the same direction of spontaneous magnetization, this magnetic domain will expand due to the advantage of low magnetostatic energy; on the contrary, the direction of spontaneous magnetization is opposite to the direction of the external field or Obtuse angled magnetic domains shrink.
Second, the irreversible displacement of the domain wall
Third, the magnetic moment of the magnetic domain rotation
Since this process is to increase the magnetocrystalline anisotropy and work, the rotation is difficult and the magnetization is also weak. The rotation of magnetic domain magnetic moments can be either reversible or irreversible. In general, both processes occur at this stage. Tile Magnets Magnetization Process
Fourth, paramagnetic magnetization stage
The characteristic of this stage is that although the external magnetic field increases greatly, the magnet manufacturer magnetization increases little. Therefore, the increase in magnetization is due in part to the reversible rotation of magnetic domain magnetic moments and partly to the improvement in the degree of misalignment of the concavity of the magnetic moment in the magnetic domain.
