Flux, Faraday Law and Lenz Law

The source defines magnetic flux, induced emf, and Lenz's law as opposition to the producing cause.

\phi=\int \vec B\cdot d\vec s

E=-\frac{d\phi}{dt}

magnetic flux

$B$

magnetic field

$E$

electric field, emf, or energy depending on context

$\phi$

magnetic flux or phase angle depending on context
