Rare Earth Sintered Neodymium Multipole Ring Magnets
Radial ring sintered magnet, a neodymium magnet manufactured, and its magnetic fields could be aligned in different directions then “normal” neodymium ring magnets. Under the manufacturing process several different magnetic fields can be created in a single ring, and in several directions. Radial neodymium rings makes it possible to create sophisticated magnetic applications in an unusual way. The classic design of magnetic rotors, for example, is being made by placing arc segments magnets on a ring, while each segment is magnetically aligned (north or south) in the opposite direction to the next magnet. With sintered radial rings, it is possible to create the opposite magnetic fields (4, 8 and more circular multi poles magnets) in a single magnet, in the same process. It is not possible in any other technology.

The advantages of radial sintered magnets are significant:
Radial Rings measure up to 150mm in diameter.
Radial sintering assures no “weak spots”.
Magnets are multi-poled – ring does not compromise the magnetic properties.
Magnetizing radially makes for a super strong magnet.
