The Neodymium (NdFeB) 636 mm Ring Magnet is a compact, highstrength rareearth magnet designed for applications that require powerful magnetic force in a small ring (donut) form factor. Manufactured from NeodymiumIronBoron (NdFeB) alloy, this magnet provides significantly higher magnetic performance than conventional ferrite magnets of similar dimensions. With an outer diameter of 6 mm, inner diameter of 3 mm, and 6 mm thickness, its ideal for use in precision mechanical assemblies, motors, sensors, magnetic couplings, fixtures, educational projects, and small DIY applications. The magnet is typically nickelplated (NiCuNi) to enhance corrosion resistance and surface durability, and is axially magnetized (through thickness), which is common for NdFeB ring magnets below 80C.
