Question

what is lenz's Law? ​

Answer 1

Lenz's law, named after the physicist Emil Lenz who formulated it in 1834, says that the direction of the electric current which is 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.

Answer 2

Explanation:

Lenz' law says that the direction of the induced current will oppose the change in flux that created it. It's not a matter of increasing and decreasing, it's a matter of direction.
