Question

Two long, straight, parallel conductors carry currents flowing in opposite directions (antiparallel currents). The magnetic force between them is:

Options

• Zero

• Attractive

• Repulsive

• Attractive if the currents are unequal

Answer 1

The direction rule states that currents flowing in opposite directions (antiparallel) produce a repulsive force between the conductors, while parallel currents produce an attractive force.
