EMF from flux B = 10t

Problem

A loop of area $S = 0{,}010 \ \mathrm{m^2}$ is immersed in a uniform field perpendicular to its plane that varies as $B = (10 \ \mathrm{T/s})\cdot t$. Calculate the induced electromotive force.

Solution

The linked flux is: $\Phi_B = B\,S = (10\,t)\cdot 0{,}010 = 0{,}10\,t \ \mathrm{Wb}$ By Faraday-Neumann’s law: $|\mathcal{E}| = \left|\ddt{\Phi_B}\right| = \ev{0{,}10 \ \mathrm{V}}$
