Solution: A long, straight wire is running through the center of a coil of wire, with the normal of the coil aligned along the length of the wire. The coil has 50 turns, a radius of 5 cm, and a resistance of 10 Ω. During a 0.05 s interval, the current in the long wire increases from 2 A to 5 A. What is the induced current in the coil of wire?
