Bonded neodymium magnetic ring is a composite material composed of neodymium iron boron magnetic material powder and adhesive. It is a circular magnet made by hot pressing or injection molding processes. It can be axially and radially magnetized (through inner or outer diameters) with multiple poles. It is mainly used for motors and generators, sensors, acoustic equipment, medical devices, instruments, and robots.
