magnet

Short Description:

Neodymium iron boron magnets (neodymium iron boron magnets) are made of three alloys of neodymium, iron and boron, and are considered to be the strongest rare earth permanent magnets in the world. Neodymium magnets have a strong attraction, which is no in proportion to its small size, and magnets can be easily processed into various shapes.
