Email us

These magnets are in high demand as their size is perfect for today& #39;s ever-shrinking electronics, sensors, and various medical devices. They are also great for hobbies, crafts, science experiments, and more! D401 Neodymium Disc Magnets are made from ultra-strong N42 NdFeB (Nd2Fe14B) and are nickel plated because Neodymium magnets oxidize very easily.
