We supply wide range of ring shape neodymium magnets in different sizes. Ring magnets have triple coating of nickel, copper and nickel again to prevent against corrosion.
The direction of the magnetism is axial on ring magnet. But you will find that it is also quite strong on the sides, although the strongest field is situated around the North direction and South direction of the poles, that are placed on the plane surfaces of these magnets.
Ring magnets are used as electric motor neodymium magnets, as ring Magnet levitation display, bearing magnets, in high-end speakers, for magnetics experiments & magnetic jewelry. And also perfect for use as magnetic fasteners around the home or for use in commercial applications.
