Two wires A and B are placed through a card. The two wires are parallel and carrying currents in the same direction, as illustrated in the figure below.
Explain why a magnetic force is exerted on each wire.
State the directions of the forces.
The detailed solution steps are locked. Click on the blue button to unlock them.
Magnetic fields are created around the two wires as current flows through them. Each wire therefore sits in the magnetic field created by the other. Now, since each wire is perpendicular to the magnetic field due to the other wire, it experiences a magnetic force. So, a magnetic force is exerted on each wire.
The force on each wire is towards the other wire, so the forces are attractive.
