Neodymium Round Magnets are available in a wide variety of grades, including N35, N38, N40, N42, N45, N50, and N52. Strong neodymium disc magnets are coated with nickel, zinc, and epoxy. Sometimes, a concave hole is drilled in the center of the disc magnet to allow it to be attached to non-metallic materials such as wood or plastic. These disc magnets allow the screw head to be located under the magnet or possibly in contact with the magnet’s surface to ensure that it does not interfere with the magnet’s performance.
NdFeB permanent magnets possess excellent magnetic properties and are widely used in electronics, electrical machinery, medical devices, toys, packaging, hardware machinery, aerospace, and other fields. Common applications include permanent magnet motors, loudspeakers, magnetic separators, computer disk drives, and magnetic resonance imaging equipment.
