Question

The drawing shows a top view of two circular coils of conducting wire lying on a flat surface. The centers of the coils coincide. In the larger coil there is a switch and a battery. The smaller coil contains no switch and no battery. Describe the induced current that appears in the smaller coil when the switch In the larger coil is closed. It flows counterclockwise, but only for a short period Just after the switch Is closed. It flows counterclockwise forever after the switch is closed. It flows clockwise, but only for a short period just after the switch is closed. It flows clockwise forever after the switch is closed.

Explanation / Answer

It flows clockwise but for a short period after the switch is closed because induced current opposes only the change in flux but after some time it becomes constant thus there will be no induced current afterwards
