Rare Earth Metal Neodymium Magnets Block Permanent NdFeB Magnets

Sintered neodymium magnets are very powerful magnets with much greater magnetism compared to other magnets, making them particularly suitable for mass production of various shapes and sizes. Accurate dimensional control can be achieved during the machining process. With these advantages, neodymium magnets have been widely used in many commercial fields such as high-performance motors, brushless DC motors, magnetic separators, magnetic resonance imaging (MRI), sensors, speakers, consumer electronics, and green energy.
