    Direction: Read the passage carefully and answer the following question.
    In the given diagram, when the magnet is pushed into the solenoid, the pointer of the galvanometer deflects slightly to the left.
    Which of the following would produce a deflection of the pointer towards the right?

    A) Move the solenoid towards the magnet.

    B) Move the solenoid away from the magnet.

    C) Move the magnet faster into the solenoid.

    D) By placing the magnet above the coil.

    Correct Answer: B

    Solution :

    Relative separation between magnet and solenoid should increase to get a deflection of pointer towards the right. It is done by moving solenoid (or magnet) away from magnet (or solenoid).
