Correct Answer

Explanation

attract each other. This phenomenon is known as the Ampere's force law. When two parallel conductors carry currents in the same direction, the magnetic fields produced by the currents interact with each other, resulting in an attractive force between the conductors. This force is proportional to the product of the currents and inversely proportional to the distance between the conductors.
