प्रश्न
A conductor of length ‘l’ is rotated about one of its ends at a constant angular speed ‘ω’ in a plane perpendicular to a uniform magnetic field B. Plot graphs to show variations of the emf induced across the ends of the conductor with
- angular speed ω and
- length of the conductor l.

उत्तर १
Induced emf (E) = `(B omega l^2)/2`

उत्तर २
i. e = `1/2 B omega L^2`
So, e ∝ ω

ii. e = `1/2 B omega L^2`
So, e ∝ L2
