Explanation: When two conductors are having currents moving in the same direction then the forces of the two conductors will be moving towards each other or attractive. Note that two wires carrying current in the same direction attract each other, and they repel if the currents are opposite in direction. The figure below shows two wires carrying currents of I = 5.05 A in opposite directions, separated by a distance d. Assume d = 11.1 cm. Why do two parallel conductors carrying current exert force on each other? Therefore, there are multiple paths through which current can flow. 7 What happens when two currents flow in the same direction? c. the two wires will exert a torque on each other.
