Question

In the above diagram, a strong bar magnet is moving towards solenoid-2 from solenoid-1. The direction of induced current in solenoid-1 and that in solenoid-2, respectively, are through the directions:

पर्याय

• AB and CD

• BA and DC

• AB and DC

• BA and CD

Answer 1

AB and DC

Explanation:

Lenz’s law states that the induced magnetic field in a wire loop will oppose the changes in magnetic flux through the loop.

Hence, using this law, we get:

The B end of solenoid-1 will behave like a south pole. So, looking at this face, the current will flow clockwise, and the direction of the current will be from A to B.

The C end of solenoid-2 will also behave like a south pole. So, looking at this face, the current will flow clockwise, and the direction of the current will be from D to C.
