Force applied to a moving Magnet in a static Electric Field?

[Xooxer]

Not sure where this should go. This is dead simple stuff, I know, but for the life of me i can't seem to find a solid answer, and I don't want to make assumptions. There's plenty of info on the motion of charged particles in magnetic fields, but not so much the other way around.

The right-hand rule describes the force a charged particle would experience traveling through a static magnetic field. What would the analogous rule be for a bar magnet moving through a static electric field?

I ask because recently I learned about Electrets, and thought it might be possible to construct a generator with only an electret and a magnet, so long as they begin in motion, and are oriented in such a way as the forced keep them in motion.

Thoughts?
