Product description

Parameters

Disc Magnets:

NdFeB Disc Magnets, Rare Earth Disc Magnets, Neodymium Disc Magnet, super neodymium Disc Magnet, Strong Disc Magnets, Rare Earth Round Disc Magnet, Sintered ndfeb Disc Magnets, Disc magnets supplier, China Disc Magnets Manufacturer

Disc size of the Neodymium Magnets are the most popular shape, which widely used in toys,sensor,relay,switch,magnetic products and other places. Almost all the disc magnets have their N and S poles on the flat face (axial magnetization), also some place are need diametrically magnetized, which must special marked when make inquiry.
