Quizplus · Accepted Answer

The magnetic force on a current-carrying wire is given by F = ILB sinθ, where I is the current, L is the length of the wire, B is the magnetic field, and θ is the angle between the direction of the current and the magnetic field. In this case, the angle θ between the direction of the current and the magnetic field is 90 degrees, so sinθ = 1. Therefore, the net magnetic force on the loop is F = ILB, and since the forces on opposite sides of the loop are equal and opposite, they cancel out, leading to a net force of zero. Therefore, the correct answer is D.
