Lenz's law states that the direction of the electric current induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes changes in the initial magnetic field. Wikipedia

Electromagnetic phenomena where changing magnetic fields induce currents with opposing fields Wikidata

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. Wiktionary
