Abstract
Active compensation in the form of a pair of trim coils and passive compensation in the form of a solenoidal-shaped magnetic shunt are disclosed for shaping the magnetic field existing in the liquid metal current collector region of an acyclic generator such as to minimize the field component normal to the stator and rotor collector surfaces and thereby substantially eliminate the generation of circulating currents in the liquid metal medium.
