A square loop of wire has a current going around it. The magnetic field from the current on each side of the loop results in a magnetic force on the wire on the opposite side. Each resulting magnetic force on the opposite side wire:

a. pushes outward on the loop
b. pushes inward on the loop
c. is actualyl zero
d. depends on if current is clockwise or counterclockwise

(a) Each resulting magnetic force on the opposite side wire, pushes outward on the loop.

Explanation:

The opposite sides of the square loop are parallel to each other.

The force between two parallel conductors is attractive in nature if the current is flowing in same direction in both conductors, whereas the force is repulsive if the current is flowing in opposite direction in the conductors.

Since the current is going around the loop of wire, it means that current on one side will be moving up and current on the opposite side will moving down. This creates currents flowing in opposite direction and causes a repulsive force between the opposite sides.

Thus, repulsive force on the opposite sides of the wire will push outward on the loop.
