Question

State and explain Lenz's law for induced emf..... ​

Answer 1

$\huge{\underline{\underline{\tt{\blue{Answer:-}}}}}$

Lenz's law states that the current induced in a circuit due to a change in a magnetic field is directed to oppose the change in flux and to exert a mechanical force which opposes the motion. ... This means that the direction of the back EMF of an induced field opposes the changing current that is its cause.
