Consider the situation shown in figure. If the switch is closed and after some time it is opened again, the closed loop will show
Options:
Answer:
D
Solution:
When switch is closed current in circuit increases suddenly and hence flux in the loop increases in outward direction so clockwise current-pulse is induced.
When switch is opened current in circuit decreases suddenly and hence flux in the loop decreases in outward direction so anticlockwise current-pulse is induced.
