NdFeb has the best performance among the rare-earth permanent magnets. It is the rare earth permanent magnet with the strongest magnetic property at present. It has an extreme high BH max and good Hcj, and greatly machinability. It is the most widely used permanent magnet material in the industrial field and known as the "Magnet King".
