Magnetization Direction
magnetized ring magnets n52

Industrial Neodymium ring magnets are one of the most popular shapes of rare earth magnets. We supply a wide range of ring magnets in different sizes. Ring magnets have triple coating of nickel, copper and nickel again to prevent against corrosion. 

Rare Earth Strong Magnetic Rings NdFeB Magnets

 

Sintered NdFeB magnetic rings are often used in joinery and shop-fitting as they may be recessed and screwed into position. Although not as strong as Neodymium Discs, the hole in center of the ring magnet ensures great versatility. The higher permeance coefficient makes neodymium ring shape magnets ideal for many applications. This type of permanent magnet can be used in science projects or experiments, medical applications, cabinetry, water conditioning, loudspeakers and other commercial and industrial purposes.
