Product Description

N42 D15x3mm NdFeB Disc Magnet With Ni Coated

Neodymium magnet(also known as NdFeB or Neo magnet), the most widly used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to the form Nd2Fe14B strusture. These magnets are widly used in many applications in modern products, such as motors in cordless tools, hard disk drives, magnetic fasterners, MRI, servo motors, lifting and compressor motors, actuators etc.
