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.
Rare 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,Thicknessetc.
