A circular loop in the plane of the paper lies in a 0.75 Tmagnetic field pointing into the paper. If the loop'sdiameter changes from 20 cm to 6 cm in 5 sec,
(a) what is the direction of the induced current,
(b) what is the magnitude of theaverage induced emf, and
(c) if the coil resistance is 2.5 ohm,what is the average induced current?
