MCQ
Consider the situation shown in figure. If the switch is closed and after some time it is opened again, the closed loop will show:
  • A
    An anticlockwise current-pulse.
  • B
    A clockwise current-pulse.
  • C
    An anticlockwise current-pulse and then a clockwise current-pulse.
  • ✓
    A clockwise current-pulse and then an anticlockwise current-pulse.
✓

Answer

Correct option: D.
A clockwise current-pulse and then an anticlockwise current-pulse.

When the switch is closed than a clock wise current pulse generated (Because initially current flow the terminal to negative terminal).
Due to Mutual Induction, current is generated in the loop. If circuit is open after some time. Dut to loop an anticlock wise current pulse generated in the circuit.
