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.

Caution:
Neodymium magnets can be dangerous, as they generate extremely strong pull forces, therefore
must be handled with care to avoid personal injury and damage to the magnets. Fingers and other
body parts can get severely pinched between two attracting magnets. Neodymium magnets are
brittle, and can shatter if allowed to slam together, launching small pieces at great speeds. Eye
protection should be worn when handling there magnets.
