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 :
The induced emf developed across the rod \[e=Blv\]
