A square coil of wire of side 3.20 cm is placed in a uniform magnetic field of magnitude 2.25 T directed into the page as in the figure shown below. The coil has 38.0 turns and a resistance of 0.780 ?. If the coil is rotated through an angle of 90.0° about the horizontal axis shown in 0.335 s, find the following.
(a) the magnitude of the average emf induced in the coil during this rotation
=___________ mV
(b) the average current induced in the coil during this rotation
=_____________ mA
