I don't think anybody uses permanent magnets in propulsion motors. Not enough field strength.

There have been studies on using rare earth magnets in electric propulsion devices, FYI. Obviously, there is a difference between permanent magnets and rare earth magnets... I'm not sure on the actual scope of research involved though... nor the result of research thus far.
