Question

Quizplus · Accepted Answer

When two parallel wires carrying current in opposite directions, they experience a force of attraction, which is known as the magnetic force. The magnetic field produced by one wire is perpendicular to the magnetic field produced by the other wire. As a result, the two magnetic fields interact, causing a force of repulsion between the two wires. Therefore, the wires push away from each other.
