1.Disc Generator Neodymium  Magnet                                                        Neodymium Magnet is Neodymium(29%-32.5%)-Iron(63.95%-68.65)-Boron(1.1%-1.2%). 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,Website: , or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B).2: Neodymium Magnet featuresDescriptionSintered Rare Earth Permanent Block Motor  Neodymium MagnetMaterialNeodymium-Iron-BoronWorking TemperatureGradeMax.
