An external magnetic field is parallel to the central axis of a 65.0-turn coil of radius 7.50 cm. During an interval of 156 ms, the field changes from 0.180 T in one direction to 0.340 T in the opposite direction. The resistance of the coil is 70.0 Ω. What is the average induced current in the coil during this interval?
