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.

Segment Magnets is one special shape of Rare earth magnets and permanent magnets.
It is always manufactured via Wire Cutting and grinding etc. Regular Segment magnets or Segment magnets have the following important factors such as, Outer Diameter Or Outer Radius, Inner Diameter or Inner Radius, Degree of Angle, Thickness, Length, Round Edge etc

Generally speaking, Segment Magnets are all made as Customer Design and as Special requirement.
Our factory produce and manufacture magnets according to customer's design on shape, dimension, grades, coatings etc.
To offer you our Arc magnets price, please offer the following details:
Magnets grade: From N35 To N52, from N Series to UH Series.
Magnets drawing with size and shape and different side view.
Magnetism direction: Mostly magnetized via diameter, if special magnetism direction, please show on the drawing in advance.
Magnets coating: Nickel, Zn, Black Epoxy, AG, Au etc.
Quantities: More mass order quantities. More Lower the prices. Original factory.
