(04.02 LC)A magnetic compass is placed 10 cm away from a simple circuit consisting of a battery, light bulb, switch, and a wire. When the switch is moved to the on position, the bulb lights up and the compass needle deflects 5 degrees to the west. If the battery was removed from the holder and resubmitted with the opposite polarity, what would occur?
