The ring-shaped magnets 15x6x6mm are made of rare earth-neodymium, which makes the magnets strong enough. Nickel and epoxy are the most common coating for rare earth neodymium ring magnets Ø15xØ6x6mm. Axial orientation let the magnetic poles lie on a flat surface. However, other coating and magnetizing directions can be customized. (More info about customization: custom neodymium magnets)The neodymium magnets rings have a small size but super strength, which is up to 5.1 kg pulling force giving the handy-sized neodymium ring magnets countless uses.
