Question

Find the magnitude of the average emf induced in the loop during its entire motion in the field.

Open in App

Solution

No. of turns $= 50$ ,
Area of square $= 0.25 m^{2}$
Magnitude of magnetic field $= 1$ T
For entire motion in the field $Δ S = 0$
$∴$ average induced emf $= N B = \frac{Δ S}{Δ t} = 0$ volt.
