Magnetic flux $\Phi _{m}=\int _{S}{\vec {B}}\cdot {\hat {n}}dA$ ▭ Electromotive force $\varepsilon =-N{\tfrac {d\Phi _{m}}{dt,}}$ (Faraday's law)
▭ Motional emf $\varepsilon =B\ell v,$ ▭ rotating coil $NBA\omega \sin \omega t$

Magnetic flux $\Phi _{m}=\int _{S}{\vec {B}}\cdot {\hat {n}}dA$
Motional $\varepsilon =B\ell v$ if ${\vec {v}}\perp {\vec {B}}$
Electromotive "force" (volts) $\varepsilon =-N{\tfrac {d\Phi _{m}}{dt}}=\oint {\vec {E}}\cdot d{\vec {\ell }}$
rotating coil $\varepsilon =NBA\omega \sin \omega t$
