Question

The magnetic force between two long parallel current-carrying conductors acts:

Options

• Perpendicular to the plane containing the two wires

• At 45° to the line joining the wires

• Along the direction of the currents

• Along the line joining the wires

Answer 1

The force between two parallel current-carrying conductors acts along the line joining the wires. It is attractive for parallel currents and repulsive for antiparallel currents.
