For the horseshoe magnet shown in the figure,the left end is a north magnetic pole and the right end is a south magnetic pole.When the switch is closed in the circuit,which way will the wire between the poles of the horseshoe magnet initially deflect?

Question

Quizplus · Accepted Answer

When the switch is closed, current flows through the wire in the direction shown by the arrows. According to the right-hand rule, the magnetic field produced by the current in the wire will create a force that is perpendicular to both the direction of current flow and the magnetic field of the horseshoe magnet. In this case, the force will be downward, causing the wire to deflect downwards.
