What are Rare Earth Magnets?
Rare-earth magnets are strong permanent magnets made from alloys of rare-earth elements.
Neodymium Magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). They are a relatively new invention and have only recently become affordable for everyday use.
Samarium cobalt (SmCo) magnets are another member of the Rare Earth magnet family, which have excellent temperature stability and corrosion resistance.
