A conducting rod $AB$ of length $l = 1 m$ is moving at a velocity $ν = 4 m s^{- 1}$ making an angle of $30 °$ with its length. A uniform magnetic field $B = 2 T$ exists in a direction perpendicular to the plane of motion, then potential difference is

Options:

Answer:

Solution:

$e = B (ν \sin 30 °) l = 4 V$

Using Fleming's right hand rule, induced current is from $B$ to $A$

$\Rightarrow V_{A} - V_{B} = 4 V$
