    The magnetic dipole moment of a current loop is independent of

    A)  magnetic field in which it is lying

    B)  number of turns

    C)  area of the loop

    D)  current in the loop

    Correct Answer: A

    Solution :

    Magnetic dipole moment of a current is given by M=NIA where N = number of turns I = current in a loop A = area of the loop From the above relation it is clear that magnetic dipole moment of a current loop is independent of the magnetic field in which it is lying.
