parallel identical loop placed a distance d above the first loop.
The directions of the currents in the two loops are both
counterclockwise. The long wavelength approximation is
applicable.

9. A small circular loop of area A is placed in the plane of, and concentric with, a large circular loop of radius R. Over the time interval from t = 0 to t = 1 s, the current in the large loop is reversed from +i, to -1, (a change in direction) at a constant rate according to i(t) = 1,(1 - 2t). The magnetic field Blarge loop produced by the large loop may be assumed to be constant...
