NdFeB Introduction: 
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.
