Question
A rectangular loop carrying a current $i_1​,$ is situated near a long straight wire carrying a steady current $i_2​.$ The wire is parallel to one of the sides of the loop and is in the plane of the loop as shown in the figure. Then the current loop will:

Answer

The magnetic field due to the straight current current carrying wire decreases with increasing distance from the wire.
Thus the magnetic field is stronger at the side closer to wire and weaker at the other.
Force on each segment of wire is $\text{BIL}$
Hence force acting on nearer side towards the wire is greater than the force acting on farther side away from wire. Hence the net force on loop is towards the wire.
