Supposing a ring of radius $y$ whose center is in the coil axis: $\varepsilon = -\frac{d\Phi_B}{dt} = -\frac{d(\vec{B}\cdot\vec{S})}{dt} = -\pi y^2 \frac{dB}{dt}$ but $\varepsilon = -\vec{E}\cdot\vec{l} = -2\pi y E$ (where $l$ is the vector in direction of induced electric current on the ring that follows the lenght of the ring) $2E = y\frac{dB}{dt}$(1) Moreover, $B(t) = \mu_0 I(t) \frac{n_0}{\ell_0}$,(2) Putting (2) into (1) and taking in account that $I(t) = I_0 \sin{2\pi\nu t}$ $E(y,t) = \frac{\mu_0 n_0 y}{\ell_0}I_0\pi\nu\cos{2\pi\nu t}$
The EFM for the coil is given by,ç $\varepsilon = - n \pi r^2 \frac{dB}{dt}$(3) From (2) and (3), $\varepsilon = -\frac{2\pi^2 r^2 n n_0 \mu_0 I_0\nu}{\ell_0}$ Calculating: $\varepsilon \simeq 0.12\;\rm{V}$
