D21 Neodymium Magnet

Email us

These miniature magnets are in high demand as they are the perfect size for use in today& #39;s ever-shrinking electronics, sensors, and various medical devices. They are also great for hobbies, crafts, science experiments, and more! The D21 Neodymium Disc Magnets are made from ultra-strong N42 NdFeB (Nd2Fe14B) and are nickel plated because neodymium magnets oxidize very easily.
