Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.

Question

The figure below shows a top view of two conducting rails on which a conducting bar can slide. A uniform magnetic field is directed perpendicular to the plane of the figure as shown. A battery is to be
connected to the two rails so that when the switch is closed, current will flow through the bar and cause a magnetic force to push the bar to the right. In which orientation, A or B, should the battery be placed
in the circuit? Hint: Use the right hand rule for the formula.
