    The intensity of magnetic field is \[H\] and moment of magnet is\[M\]. Then the maximum potential energy will be

    A) \[4MH\]                              

    B) \[3MH\]

    C) \[2MH\]                              

    D) \[MH\]

    Correct Answer: D

    Solution :

    Intensity of magnetic field\[=H\] Magnetic moment\[=M\] The potential energy is given by \[U=-MH\sin \theta \] Hence, the maximum potential energy is \[U=-MH\sin {{180}^{o}}\] (for maximum potential energy \[\theta ={{180}^{o}}\]) \[=-MH(-1)=MH\]
