Two long parallel wires carry identical electric currents in the same direction. Then they will :

Correct option is B

The correct answer is: (b) Attract each other
Explanation: When two current-carrying wires carry current in the same direction, they produce magnetic fields that cause mutual attraction.
Information Booster: • Parallel currents → attract • Anti-parallel currents → repel • Based on Ampere’s force law and Biot–Savart law
