Lenz's law - Definition, Explanation

A law in physics: in electromagnetic induction, any induced current always flows in a direction so as to oppose its source; formulated in 1833 by German physicist Heinrich Lenz (1804–65). Were this not so, perpetual motion machines could be built. The law is responsible for speed self-regulation in electric motors.
