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. $Bv^{2}L$
• C. $\frac{BL}{v}$
• D. $BL^{2}v$

Answer 1

Answer: (A)

$BLv$

Answer 2

The induced emf developed across the rod
$e=Blv$
