Chapter 31, Problem 31.9OQ

Two coils are placed near each other as shown in Figure OQ31.9. The coil on the left is connected to a battery and a switch, and the coil on the right is connected to a resistor. What is the direction of the cur-

Chapter 31, Problem 31.9OQ, Two coils are placed near each other as shown in Figure OQ31.9. The coil on the left is connected to

rent in the resistor (i) at an instant immediately after the switch is thrown closed, (ii) after the switch has been closed for several seconds, and (iii) at an instant after the switch has then been thrown open? Choose each answer from the possibilities (a) left, (b) right, or (c) the current is zero.
