Neodymium Ring Magnets

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.

Neodymium Ring Magnets

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.

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. The higher permeance coefficient makes Neodymium ring magnets ideal for many applications.

Neodymium rings are one of the most popular shapes of rare earth magnets. TCM 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.

For iron component (about 66%), it is easy disadvantages oxidizing power is strong rust there often (neodymium magnet) Nd-Fe-B sintered magnet. Surface treatment that a mandatory essential to prevent it, there is a method using various materials in it. To determine the material of plating depending on the environment used is neodymium.
