Diagram 1 illustrates a wire that is carrying an electric current. The wire is positioned between the poles of a magnet. The current and the magnetic field together exert an upward force on the wire, as indicated. In diagram 2, both the magnetic poles and the current are reversed. In diagram 2, which way does the force act on the wire?
- Adownwards
- Btowards the North pole of the magnet
- Ctowards the South pole of the magnet
- Dupwards
