Sintered Rare Earth Magnets Special Magnets NiCuNi Coated Permanent Magnet For Generator

1. What is Neodymium Magnet


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 thenground 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.
