A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, thus that an emf of 0.57 V and a current of 5.7 A are induced in the coil. The wire is then re-formed into a single-turn square coil, which is utilized in the same magnetic field (again perpendicular to the plane of the coil and with a magnitude changing at the similar rate). What (a) current are induced in the square coil and (b) emf
