Lets say you have a plastic plate with little charged balls around the edge. in the middle there's a coil with a current going through. now if the current is suddenly stopped then there's a change in the magnetic flux through the plate so as a result there should be an electric field circulating around the plate. this would push the balls and the plate would spin. but doesn't this contridict AM conservation. could the answer be that the new electric field produces a new magnetic field which induces another EF in the opposite direction so the plate doesn't spin? Thanks.
