Neodyminum Iron Boron( NdFeB) magnets are alloys of the Lanthanide group of elements. Rare Earth magnets are the most advanced commerclialized permanent magnet materials today. Sintered NdFeB magnets offer the highest energy product of any material today and are avaiable in a very wide range of shapes, sizes and grades and application requirements. It is generally used in motors, speaker, toys and electronics.
