IIRC it depends on the frame of reference. Relative to a magnetic field, the only thing a magnetic force does is changing the velocity direction of affected objects. All work regarding the absolute magnitude of the velocity is zero (no lateral acceleration).

How fucking smart do you think 5 year olds are?
When you hold two strong magnets an inch apart, then let them go it looks like they move themselves (add velocity)?
What makes the magnets start moving towards each other from a complete stop?
