Neodymium Iron Boron (Neodymium Magnets)

NdFeB (Neodymium Iron Boron / Neodymium Magnets) is fast becoming one of the most popular materials.  This is due to its extremely high energy product and linear demagnetisation curve making it a very useful magnet. Neodymium Magnets, in many applications, has to be coated to prevent corrosion as NdFeB magnets are extremely corrosive when introduced to water.  Neodymium Magnets also do not work as to a high temperature as other materials.
