(D) According to Faraday's law of electromagnetic induction, the magnitude of induced $e.m.f.$ is given by $|e| = N \left( \frac{d\Phi}{dt} ight) = N \left( \frac{d(BA \cos 	heta)}{dt} ight).$
Since the coil is placed normal to the magnetic field, the angle $	heta = 0^\circ$, so $\cos 0^\circ = 1$.
The area of each square loop is $A = (side)^2 = (10 	imes 10^{-2}\, m)^2 = 10^{-2}\, m^2$.
Given $N = 500$, $\frac{dB}{dt} = 1.0\, T/s$, and $A = 10^{-2}\, m^2$.
Substituting these values: $|e| = 500 	imes 1.0 	imes 10^{-2} = 5\, V$.

$A$ coil having $500$ square loops each of side $10\, cm$ is placed normal to a magnetic flux which increases at the rate of $1.0\, T/s$. The induced $e.m.f.$ in volts is:
