76.

Ans - Let the side of the loop nearer to the straight wire is attracted towards the straight wire with a force f1 anf the opposite side repelled by the straight wire with a force f2.

Since the current in the side of the loop nearer to the wire is in the same direction as the straight wire, we get f1>f2.

Hence,

loop moves towards the wire.
