An induced electric current always flows in such a direction that it opposes the change producing it. This law, first stated by Heinrich Lenz (1804–65) in 1835, is a particular example of the law of conservation of energy.

When a magnetic field and an electrical circuit are moved in relation to one another, an electric current is induced in the circuit such that it forms a magnetic field opposing the motion.
