Solve this obe In the figure shown two loops ABCD & EFGH are in the same plane. The
smaller loop carries time varying current I = b t, where b is a positive
constant and t is time. The resistance of the smaller loop is r and that of
the larger loop is R : (Neglect the self inductance of large loop). The
