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
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.
