    A bar magnet of magnetic moment M is cut into two parts of equal length. The magnetic moment of each part will be

    A)  12 M

    B)  M

    C)  0.5 M

    D)  zero

    Correct Answer: C

    Solution :

     Magnetic moment = M. Also from the formula we have magnetic moment M = pole strength \[\times \] length. Since, the pole strength of each part remains the same and it becomes half, therefore, magnetic moment of each part will be\[\frac{M}{2}=0.5M\]
