Two loops of wire are arranged so that a changing current in one, the primary, will induce a current in the other, the secondary. The secondary loop has twice as many turns as the primary loop. The current in the primary at this moment is 6 A and increasing. The current in the secondary must be:
a. 3 A. b. 6 A. c. zero. d. There is insufficient information to work this problem.
