Where can you find bonded neodymium disc magnets being used? Air bags, anti-lock brakes, medical instruments, toys, and credit card coding systems—just to name a few places. This type of magnet combines powerful neodymium magnetic powder with a non-magnetic polymer or rubber binder. The end product is a corrosion-resistant, machinable magnet that offers intense magnetic strength while minimizing dimensions. If you need a powerful magnet to fit into a tight spot, bonded neodymium disc magnets are an excellent choice.
