  1. Question 1

    Q1. Two parallel wires carrying currents in the same direction attract each other because of:

    • A) Potential difference between them
    • B) Mutual inductance between them
    • C) Electric forces between them
    • D) Magnetic forces between them

    Answer: Magnetic forces between them

    Explanation: Parallel wires carrying currents in the same direction create magnetic fields that interact — by the right-hand rule and Ampere's force law, the magnetic force between them is attractive.
