A scientist runs an electric current along a wire. A magnetic compass is
placed near the wire. The scientist observes that whenever the current is
turned on, the compass needle moves. Why does the compass needle
move?
O The current creates an electric field around the wire
O The current creates a magnetic field around the wire
O The current adds electric charge to the compass needle
O The current increases the force of gravity on the compass needle
