  • At time  magnetic field of  Gauss is passing perpendicularly through the area de

At time t=0 magnetic field of 1000 Gauss is passing perpendicularly through the area defined by the closed loop shown in the figure. If the magnetic field reduces linearly to 500\: Gauss, in the next 5s, then induced EMF (in \mu V) in the loop is : 
Option: 1 56

Area of the given loop

\\A=Area\ of\ rectangle-Area\ of \ 2\ triangles\ with\ height\ 2cm \\ A=16\times4-2\times4=56cm^2

Magnitude of emf 

\\E=A\frac{dB}{dt}=56\times10^{-4}\times(\frac{(1000-500)\times10^{-4}}{5})\\ E=5600\times10^{-8}V=56\mu \ V

So the correct graph is given in option 1.
