Anisotropic Ferrite Magnets

Anisotropic magnets are magnets whose magnetization directions in the magnets are aligned in a certain direction.


Magnet powder for anisotropic magnets is composed of a single crystal or polycrystal with an aligned direction of magnetization in one magnet particle. When a magnetic field is applied externally during molding (this magnetic field is called an aligning magnetic field), the magnet powder moves to align with the direction of the magnetic field and is solidified in an aligned state, resulting in an anisotropic magnet. Magnet powder aligned with an aligning magnetic field is solidified with keeping magnetization. Therefore, after removing the alignment magnetic field, the molded body becomes a magnet having a magnetic force.
