Detailed Solution

Given data:

Current carrying wire is placed

If current increases

Concepts used: magnetic field

Explanation:

The lines of the magnetic field due to PQ inside the coil are directed inwards the paper plane. Since the current in PQ is continuously increasing, the flux through the loop is also continuously increasing. According to Lenz's law, the current in a loop flows in a direction that cancels out the increase in magnetic flux through the loop. Therefore, the magnetic field caused by the induced current in the circuit must be projected out of the paper. Therefore, the current must flow counterclockwise according to the right-hand rule.
