Question

8) A coil of area 4 cm2 is subjected to a normal magnetic field, which changes from 2T to 1T in 25 sec. find the EMF induced across the coil

Answer 1

Dear Student.
$$\begin{gathered} E=\frac{changeinflux}{timetaken}=\frac{\left(2-1\right)4*{10}^{-4}}{25}=0.16*{10}^{-4}volt \\ Regards \end{gathered}$$
