NdFeB magnet:
A permanent magnet is an object made from a material that is magnetized and creates its own
persistent magnetic field. These include the elements iron, nickel and cobalt, some alloys of
rare-earth metals, and some naturally occurring minerals such as lodestone. Although
ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly
enough to be commonly considered magnetic, all other substances respond weakly to a
magnetic field, by one of several other types of magnetism.

The 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.
Advantages of Sintered Magnet
1.Extreme strong Br Resident induction.
2.Excellent demagnetization resistance capability.
3.Good Price relative to its high magnetic properties.
