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 compass was moved 5 cm closer to the circuit, what would occur? O The deflection of the needle would decrease The deflection of the needle would increase. The needle would not move from its position. O The needle would deflect in the opposite direction
