154706 A conducting rod of length $L$ is moving in a uniform magnetic field (B) 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?
