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.
