A wire-loop confined in a plane is roated in its own plane with some angular velocity. A uniform magn etic field exists in the region. Find the emf induced in the loop.

Solution

i = $v (B \times l)$

= $v B l . c o s Θ$

$Θ$ is the angle between normal to plane and B which is $90^{0}$

Hence emf induced = $90^{0}$

So, i = $v B l c o s 90^{0} = 0$

A wire-loop confined in a plane is roated in its own plane with some angular velocity. A uniform magn etic field exists in the region. Find the emf induced in the loop.

i = v(B×l) = vBl.cos Θ Θ is the angle between normal to plane and B which is 900 Hence emf induced = 900 So, i = vBl cos 900=0

i = $v (B \times l)$

= $v B l . c o s Θ$

$Θ$ is the angle between normal to plane and B which is $90^{0}$

Hence emf induced = $90^{0}$

So, i = $v B l c o s 90^{0} = 0$
