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?

• The current creates an electric field around the wire.

• The current creates a magnetic field around the wire

• The current adds electric charge to the compass needle.

• The current increases the forces of gravity on the compass needle.
