Question

magnetic flux associated with the coil changes by 0.04 WB in 0.2 seconds find the induced emf
​

Answer 1

Given: Change in magnetic flux, $\phi_{B}$ = 0.04WB

Change in time, Δt = 0.2s

Find: Here, we have to find the induced emf,

Solution:

We know the expression of the induced emf in the coil is

$\varepsilon = \dfrac{d\phi_{B} }{dt} \\\\\varepsilon = \dfrac{0.04}{0.2}\\\\\varepsilon = 0.02 Volts$

So, the induced emf is 0.02Volts
