NdFeB permanent magnet is mainly used in Micro-motor, Electronic Industry, Car Industry, Petrochemical, NMR devices, Sound equipments, Maglev System, Magnetic drive and Magnetotherapy system, and its also used in Motorbikes, Car oil-duct's magnetization, with the aim of saving oil.
Earth permanent magnet (NdFeB) has the strongest magnetism nowadays. It does not only has high remanence, high coercivity, high energy product, and high-functional, but also it can processed into a variety of sizes easily. Now, it is widely used in avigation, spaceflight, electron, electrical sound, electrical machinery, apparatus, meters, medical technology, and especially apply to develop high-performance, small and light replacements.

Ring Magnets is one popular shape of Rare earth magnets and perment magnets.
It is always manufactured via Cutting, Slicing, Drilling, and grinding etc. Ring magnets have the following important factors such as, Outer Diameter, Inner Diameter, Thickness etc.

Our factory produce and manufacture magnets according to customer's design on shape, dimension, grades, coatings etc.
To offer you our Ring magnets price, please offer the following details:
Magnets grade: From N35 To N50, from N Series to UH Series.
