A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, so that anemf of 0.69 V and a current of2.8 A are induced in the coil. The wire isthe re-formed into a single-turn square coil, which is used in thesame magnetic field (again perpendicular to the plane of the coiland with a magnitude changing at the same rate). What emf andcurrent are induced in the square coil?
