Neodymium Ring Magnet manufacturer & supplier
Rare Earth Ring Magnets, also known as neodymium ring magnets, 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 centre of the ring magnet ensures great versatility. Ring Tube Neodymium Permanent Rare Earth Magnets
Sintering Nd Magnetic Ring N42
Neodymium rings are one of the most popular shapes of rare earth magnets. MPCO Magnetics manufactures a wide range of ring magnets in different sizes and with several different coatings such as Nickel, Zinc, Epoxy or Gold to prevent and reduce wear and corrosion.
Strong Neodymium Ring Magnets N35, N38, N42, N45, N50 & N52. Neodymium Ring Magnets are widely used in such applications as holding, motors, consumer electronics, medical, sensors and speakers. Due to the high magnetic strength of a Rare Earth Magnet, it has replaced other magnetic materials in order to make a design smaller but achieve the same result.

Through the Thickness: Ring magnets where a magnetic field travels from the ID of the ring magnet to the OD of the ring magnet. Diametrically Ring Magnets
Radially Magnetized: Radially magnetized ring magnets have the magnetic poles on the OD / ID instead of the face. Radial magnets are made as a single piece or in multiple pieces depending upon the size of the magnet. A list of radial rings is available under our Radial Ring magnet section.
