There are two coils A and B as shown in Fig.

A

When switch S is closed, the direction of the momentary current induced in coil B will be in anticlockwise direction

B

When switch S is closed, the direction of the momentary current induced in coil B will be in clockwise direction.

C

When switch S is opened, the direction of the momentary induced current in coil B will be in clockwise direction

D

When switch S is opened, the direction of the momentary induced current in coil B will be in anticlockwise direction.

Text Solution

Verified by Experts

The correct Answer is:
A, C
According to Lenz's law, current in coil A grows in clockwise direction (when switch S is closed). This causes increases in magnetic flux linking the coil B in clockwise direction. Therefore, current is induced in coil B in anticlockwise direction. Similarl, when switch is opened, magnetic flux linked with coil B decreases. The direction of induced current in coil B will be clockwise.
