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?

Question

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? (A)  BLv  (B)  Bv2L  (C)  (BL/v)  (D)  BL2v

The induced emf developed across the rod e=Blv

$B Lv$

$B v^{2} L$

$\frac{B L}{v}$

$B L^{2} v$

The induced emf developed across the rod
$e = Bl v$
