A square coil of wire of side 2.80 cm is placed in a uniform magnetic field of magnitude 1.25 T directed into the page as in Figure P20.31. The coil has 28.0 turns and a resistance of 0.780Ω. If the coil rotated Figure P20.31 through an angle of 90˚ about the horizontal axis shown in 0.335 s, find (a) the magnitude of the average emf induced in the coil during this rotation and (b) the average current induced in the coil during this rotation.
