State and explain Lenz's law.
State and explain Lenz's law.
Last answer:
Lenz’s law: It states that the direction of statically induced emf is such that it always opposes the cause that produces it. In fact, the induced emf produces current, which produces magnetic flux and this magnetic flux opposes the changing magnetic field that is responsible for emf induction.
