What does Lenz's law mean?

The induced current in a loop is in the direction that creates a magnetic field thatopposes the change in magnetic flux through the area enclosed by the loop (That is, the induced current tends to keep the original magnetic flux through the circuit from changing). This is what Lenz's law states.

named after the physicist Heinrich Lenz who formulated it in 1834, says: 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.
