1. The problem statement, all variables and given/known data A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, so that an emf of 0.76 V and a current of 3.1 A are induced in the coil. The wire is the re-formed into a single-turn square coil, which is used in the same magnetic field (again perpendicular to the plane of the coil and with a magnitude changing at the same rate). What emf and current are induced in the square coil? 2. Relevant equations I=ER 3. The attempt at a solution i found the emf (.589V) but i can't figure out the current. what do i do?
