Arc Neodymium Magnet with epoxy black coating Neodymium magnet (NdFeB), commonly known as "rare earth" magnet, is a high-performance permanent magnet made of neodymium, iron and boron alloys. They are real permanent magnets and will not lose their magnetism unless heated to a temperature exceeding the maximum operating temperature rating or their protective coating is damaged. Characteristic: -Energy products may exceed 50mgoe -Low corrosion resistance Applications: -automotive -electronics (sensors, speakers, scanners) -medical (scanners) -magnetic separators

Strong Self-adhesive Disc Magnets This set of strong Self-adhesive Disc Magnets include two strong neodymium magnets with matching north/south poles and 3M Adhesive. Neodymium Rare Earth is a type of permanent magnetic material that offers a strong magnetic force. They also have a 3M Adhesive on each magnet.
