"Work" is done by forces acting on a body that ostensibly obeys the law of inertia. I would say the least perplexing explanation is the magnetic field transforms the law of inertial motion into a law of circular motion. This transformation could be called work-with-out-force. Of course this kind of "work" is inconceivable within conventional physics because it treats the first law of motion as an absolute or inflexible principle. Harry
