b a (b much greater than a) and resistance R1. A timedependent voltage is applied to the larger loop; its slow sinusoidal variation in time is given by V(t) = V0 sin θ t, where V0 and are constants with dimensions of voltage and inverse time, respectively. Assuming that the magnetic field throughout the inner loop is uniform (constant in space) and equal to the field at the center of .
