Two concentric, coplanar conducting loops share the same center. A clockwise current in the smaller inner loop is increasing in magnitude. Which of the following best describes the direction of the induced current, if any, in the larger outer loop?
(a) A clockwise current is induced.
(b) No current is induced because the loops are coplanar.
(c) A counterclockwise current is induced.
(d) Alternating clockwise and counterclockwise currents are induced.
