Physicist Emil Lenz (pronounced /ˈlɛnts/) formulated Lenz's law in 1834, after which it was named for him.

Magnetic fields[edit]

"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 field that opposes the change that produced it."[1]

For current I that generates a magnetic field

'"`UNIQ--postMath-00000001-QINU`"'

The induced current generated

'"`UNIQ--postMath-00000002-QINU`"'

Theoretical Lenz's law[edit]

Def. "a law of electromagnetic induction which states that an electromotive force, induced in a conductor, is always in such a direction that the current it would produce would oppose the change which caused it; it is a form of the law of conservation of energy"[2] is called Lenz's law.
