Suppose I have a conducting bar moving over a constant magnetic field. A Lorentz force arises on the charges that constitute the bar, polarizing the bar, and generating what is called motional emf.
How can I explain this from the bar's point of view? From its own reference frame, the bar is not moving, and the magnetic field is uniform. So what causes the emf?
