Problem: A small circular loop of wire of radius 0.05 m and reisstance 1.0x10 -3 Ω is centered inside a large circular loop of wire of radius 0.5 m. The larger loop, which initially carries a current of 8.0 A, is cut and its current is reduced to zero over a time inteval of 1.0x10-6 s. Find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop).
