Arc magnet also called as magnetic tile , it is a kind of permanent magnet in tile shape, mainly used on permanent magnet motor. Neodymium arc magnets are the special shape of rare earth permanent magnets. This type of super power magnets is always made via wire cutting and grinding etc. Regular arc magnets or segment magnets have the following important factors such as outside diameter or outer radius, inside diameter or radius, the degree of angle, thickness, length, round edge etc. Most of the neodymium arc magnets (neodymium segment magnets)are just produced for industrial production. Such as motor magnet, rotor magnets. Neodymium arc/segment magnets are mostly magnetized through diameter. Generally speaking, arc/segment magnets are all made upon customer design. So please provide very detail information before offer and production. Meank magnetic can supply all kinds of strong power arc/segment magnets for different aspects of the industry.
