Lenz's law

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.
