- Perpendicular magnetic field pressing
- A method of pressing a permanent magnet with single axis anisotropy in which the direction of the magnetic field applied in order to orient the magnetic powder within the magnetic field in the manufacturing process is perpendicular to the pressing pressure direction. This is also called horizontal magnetic field pressing. On the other hand, the pressing method in which the magnetic field direction and pressing direction are parallel is called parallel magnetic field pressing (vertical magnetic field pressing). Because the orientation state of the magnetic particles is not disrupted during pressing, the product's magnetic characteristic is higher than for parallel magnetic field pressing. However, in some cases the product shape and magnetization direction make perpendicular magnetic field pressing impossible.
