Ring 40H black epoxy NdFeB magnet
Neodymium magnets also known as NdFeB magnets are the third generation of rare earth permanent magnets, they are composed of Neodymium, Iron, Boron and a few transition metals. Neodymium magnets have high remanence, high coercive force, high energy product and high performance. Currently Neodymium magnets are the strongest magnets available in the world.
They are widely used in automobiles, mobile phones, digital cameras, jewelry, clothing, all kinds of hardware accessories, electrical, laser heads, toys, gifts, speakers, packing, leather goods, medical equipment and adverying, Switchboard, voice coil motors (VCM's) in hard disk drives, high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors, loudspeakers etc.
