Answer 1

Explanation:

The direction of magnetic field in ring P owing to current in wire will be perpendicularly outward from plane of paper, according to the right hand thumb rule.

When the current in the wire increases, the direction of induced current in ring P will be such that it opposes the increasing current in the wire, according to Lenz's law. The ring's upper face serves as the South pole, while the lower face serves as the North pole. As a result, the clockwise direction of induced current in ring P.

Similarly, the anti-clockwise direction of generated current in ring Q.
