Question

Consider the conducting square loop shown in the figure. In the given adjacent circuit , the switch is closed and after some time it is opened again, the closed loop will show-

• A. An anticlockwise current-pulse and then a clockwise current-pulse
• B. A clockwise current-pulse
• C. A clockwise current-pulse and then an anticlockwise current-pulse
• D. An anticlockwise current-pulse

Answer 1

The correct option is D An anticlockwise current-pulse

According to lenz's law, an anti-clock wise current is induced in the conducting loop , to oppose the change in the magnetic flux linked with loop as shown in figure.
