Question

A long straight wire carrying current I and a square conducting wire loop of side l , at a distance 'a' from current wire as shown in the figure. Both the current wire and loop are in the plane of paper. Find the magnetic flux of current wire, passing through the loop.

Answer 1

Explanation:

move towards the wire explanation as two like current attract and unlike current repel each other thr wire will attract the side of the loop near the wire and parallel to it and the far side of the force of attraction will be be repelled but the force of attention will be more as that side of the loop is closer to the wire and so effective the current loop will move towards the wire
