Faraday's law
Faraday’s law states that a changing magnetic flux through a loop induces an emf (electromotive force) in the loop.
Lenz's law
Lenz’s law states that the direction of the induced emf is such that it opposes the change in magnetic flux that produces it.
This principle ensures the conservation of energy.
Magnetic flux
Magnetic flux $\Phi$ quantifies the amount of magnetic field passing through a given surface.
