    A conducting rod of length L is moving in a uniform magnetic field with a velocity v without rotation. The velocity of the rod is perpendicular to the rod, and the motion of the rod is confined to a plane perpendicular to the magnetic field. What is the induced emf developed across the rod?

    A)  \[BLv\]

    B)  \[B{{v}^{2}}L\]

    C)  \[\frac{BL}{v}\]

    D)  \[B{{L}^{2}}v\]

    Correct Answer: A

    Solution :
