The circular coin shaped neodymium magnet with different diameter and thickness are known as neodymium disc magnet or NdFeB or rare earth disc magnets .Neodymium (also known as "NdFeB", "NIB" or "Neo") disc magnets have far stronger magnetism than all other round permanent magnet, and they are the most powerful disc magnets today. Because neodymium disc magnets have powerful magnetic strength, moderate price and can perform well at ambient temperature, they are the most important magnet components in industrial production.Generally,one circular plane of the industrial neodymium(NdFeB) disc magnet is the north pole and the other circular plane is the South Pole,that is axially magnetized neodymium disc magnets. All our NdFeB disc magnets are provided as axially magnetized,unless otherwise specified.
