    The deflecting torque acting on the coil of a galvanometer is

    A) inversely proportional to number of turns.

    B) inversely proportional to current flowing.

    C) inversely proportional to area of the coil.

    D) directly proportional to the magnetic field strength.

    Correct Answer: D

    Solution :

    Option [d] is correct. Explanation: \[\tau \] = nBIA. So, torque is directly proportional to the magnetic field strength, area of the coil, number of turns and current flowing.
