Neodymium NdFeB Mini Spherical Magnets Ball
Neodymium Iron Boron (NdFeB) magnets are composed of Nd, Fe, B, Dy, Co and other minor elements. They have excellent magnetic property and are extremely strong for their small size. NdFeB magnets are permanent, and have a high maximum energy product. Over the last 10 years, due to high ratio of performance over price, the NdFeB magnet has become extremely popular in almost all technology applications that require high performance magnets.
They are used in devices and instruments where a strong magnetic field is required, such as in avionics, spacecraft, electronic instruments and test equipment, medical instruments, microphones, DC motors, loudspeaker drivers, magnetic therapy products.
