A magnetic field is perpendicular to the plane of a single turn circular coil. The magnitude of the field is changing so that the emf of 0.80 V and a current of 3.2 A are induced in the coil. The wire is then re-formed into a single turn square coil, which is used in the same magnetic field (again perpendicular to the place of the coil and with the magnitude changing at the same rate). What emf and current are induced in the square coil?
