Quizplus · Accepted Answer

The force on a current-carrying wire in a magnetic field is given by F = ILB sinθ, where θ is the angle between the current direction and the magnetic field. For section BC, the current is parallel to the magnetic field, making θ = 0 degrees, and sin(0) = 0, resulting in zero force.
