A small loop lies outside a circuit. The key of the circuit is closed and opened alternately. The closed loop will show
Text Solution
Verified by ExpertsThe correct answer is:
D
When key is closed dots are linked with closed loop (i.e. increases from zero to a certain value) so induced current will be clockwise when key is opened dots linked with loop decreases (from a certain value to zero) so induced current will be anticlockwise in direction.
