Abstract
Apparatus and methods to magnetize and demagnetize the magnetic poles of a rotor assembly for an electrical machine, such as a generator. The apparatus and methods provide for individually magnetize magnetic domains in the permanent magnetic material of the magnetic poles of a rotor assembly of the electrical machine after the electrical machine is installed in a larger assembly. The magnetization system may be used to magnetize and demagnetize the magnetic poles while the rotor assembly is connected with a prime mover, such a rotor of a wind turbine.
