Lenz's law gives the direction of the induced emf resulting from
electromagnetic induction, thus:
- The emf induced in an electric circuit always acts in such a direction that the current it drives around the circuit opposes the change in magnetic flux which produces the emf.
The law is named after the Russian physicist Heinrich Lenz[?].
See Maxwell's equations for further mathematical treatment.
