N35 Rare earth radial Countersunk Permanent NdFeB Magnet ring
Product Description:
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.

Advantages of Sintered Magnet
* Extreme strong Br Resident induction.
* Excellent demagnetization resistance capability.
* Good Price relative to its high magnetic properties.
Cautions:
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.
