Answer:
Magnitude of induced emf will be [tex]2.437\times 10^{-3}volt[/tex]
Explanation:
We have given radius of the circular loop r = 19.7 cm = 0.197 m
So area of the circular loop [tex]A=\pi r^2=3.14\times 0.197^2=0.1218m^2[/tex]
It is given that magnetic field is changing as [tex]2\times 10^{-3}T/sec[/tex]
Emf induced in the circular loop is equal to [tex]e=\frac{-d\Phi }{dt}=-A\frac{dB}{dt}[/tex]
So emf induced will be equal to [tex]e=\frac{-d\Phi }{dt}=-0.1218\times2\times 10^{-3}=2.437\times 10^{-3}volt[/tex]
So magnitude of induced emf will be [tex]2.437\times 10^{-3}volt[/tex]
