Question

what is Lenz's law?
need expert verify answer

Answer 1

Answer:

Lenz's law, named after the physicist Emil Lenz who formulated it in 1834, says 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.

Explanation:

Answer 2

Answer:

Lenz's law states that when an emf is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced emf is such, that it produces an current whose magnetic field opposes the change which produces it.
