The figure shows two parallel loops of wire having a common
axis. The smaller loop (radius r ) is above the larger
loop (radius R) by a distance x >> R.
Consequently, the magnetic field due to the counterclockwise
current i in the larger loop is nearly constant throughout
the smaller loop.
Suppose that i, the current in the larger loop is shut
off, and decreases at the constant rate
di/dt.
