Rare earth magnets and alloy powder for rare earth magnets and their manufacturing methods.
Permanent rare-earth magnets are placed around the tube to establish an octupole magnetic guiding field leading from the source chamber to the MOT.
Sintered rare earth magnets are manufactured by a powder metallurgical process which involves the sintering of powder compacts under vacuum.

The rare earth magnets can be mounted to either the front or rear face on the crank pulley or flywheel.
Using rare earth magnets is normally the only way to get high efficiency from a low-Voltage motor.

Rare earth magnets are extensively used in magnetically shielded designs since their small size allows them to be contained totally within the motor structure, thereby minimizing the external field.
Rare-earth magnets, of which the most common type is samarium cobalt, are stronger for a given weight and volume than ferrite magnets.
If rare earth or superconducting magnets had been available in the days of Faraday and Maxwell the one-piece homopolar machine might have become an article of commerce.
