According to the application,the magnetized direction of neodymium(NdFeB) magnet tiles generally divided into radially magnetized and diametrically magnetization.Please let us know the magnetization direction when you send us inquiry for rare earth neodymium magnet tiles
Neodymium magnetic tiles are custom motor magnets,sintered Nd-Fe-B material has good machinability and can be customized into different types of magnet tiles,mould is not necessary for customizing neodymium magnetic tiles.We can supply neodymium tile magnets for all kinds of motors.Please provide drawings when you inquiry and order rare earth neodymium magnetic tiles.
