    Answer : Option D

    Explanation :

    The pole strength of each piece when a bar magnet is cut into two equal halves perpendicular to its length is the same as the pole strength of the original bar magnet. However, the magnetic moment of each piece is half the magnetic moment of the original bar magnet.
