NdFeB Permanent Magnet production process:
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.
Neodymium block magnet, also known as rectangular magnet, square magnet or bar magnet, compared with disc magnet, block magnet is not as commonly used as disc magnet, but their straight line and clean edge offer a pleasing and different visual appearance, what's more, it provides a bigger surface area than disc magnet of same diameter.
Block magnet is usually magnetized with north and south pole on opposite square faces, also a multi poles magnetized block is possible with a new magnetizer machine.
