Vedclass · Answer

(D) The induced $emf$ $(e)$ in a moving conductor is given by the motional $emf$ formula $e = Blv$,where $l$ is the length of the conductor moving perpendicular to the magnetic field.In this case,only the side of the loop that is inside the magnetic field and perpendicular to the velocity vector contributes to the induced $emf$.The length of the side of the loop is $L$. As the loop moves with velocity $v$,the side of length $L$ cuts the magnetic field lines.Therefore,the induced $emf$ is $e = B L v$.The magnitude of the induced $emf$ is $vBL$.
