A small circular loop of wire of radius 5.0 cm and resistance R = 9.0 10-4 Ω is centered inside a large circular loop of wire of radius 50 cm (see figure below). The larger loop, which initially carries a current I = 6.5 A, is cut and its current is reduced to zero over a time interval of 1.2 10-6 s. Find the average current in the smaller loop during this time interval. (The magnetic field of the larger...
