A small circular loop of wire of radius 5 cm and resistance 1E-3 Q is centered inside a large
circular loop of wire of radius 50 cm. The larger loop, which initially carries a current of 8 A, is
cut and its current is reduced to zero over a time interval of 1E-6 s. Our goal will be to 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.)
