1. The problem statement, all variables and given/known data A box of wire is moving within a constant B field. Is there an induced current? 2. Relevant equations Slap rule 3. The attempt at a solution Since the wire is experiencing constant B field, how would we figure out whether or not there is a current? I know there is a current if the B field is changing (Faradday's law) but if it is in a constant B field, I don't think there would be a current?
