Lenz's Law

Lenz's law (pronounced /ˈlɛnts/), named after the physicist Emil Lenz who formulated it in 1834

The direction of current induced in a conductor by a changing magnetic field due to Faraday's law of induction will be such that it will create a magnetic field that opposes the change that produced it.

The current that profuces magnetic field is

$B=LI$

The induced current will create a magnetic field that opposes the change that produced it.

$\phi =-NB=-NLI$
