Radially magnetised magnets

Radially magnetised magnets are rare due to a complex manufacturing process. Radially magnetised magnets are mostly used in motors and generators, as well as in free energy experimentation and rare earth permanent frictionless bearings.
This cylindrical Neodymium magnet has been radially magnetised with the north polarity on the inside and south on the outside. The outer diameter is 40mm and inner diameter is 30mm with a stainless-steel ring on the outside.


Radial Ring Magnets are manufactured with the north and south pole on the outside diameter (OD) and inside diameter (ID). These can be used as motor magnets, sensor magnets, and any applications were multiple or single poles are required on the OD or ID of the magnet.

Application of Cylinder Rotor NdFeB Magnetic Assembly
Linear Halbach arrays:
Such as the brushless AC motor, voice coils, magnetic drug targeting to high-tech applications such as wiggler magnets which are used in Particle acceleratorsand Free-electron lasers. neodymium halbach array magnetic assemblies
Halbach cylinder:
Such as brushless AC motors, magnetic couplings and high field cylinders. Both brushless motors and coupling devices use multipole field arrangements.
