WebLenz's law is a consequence of conservation of energy applied to electromagnetic induction. It was formulated by Heinrich Lenz in 1833. While Faraday's law tells us the magnitude of the EMF produced, Lenz's law tells us the direction that current will flow. It states that the direction is always such that it will oppose the change in flux which ... WebApr 1, 2024 · For CD, the magnetic flux decreases with time i.e. $\dfrac{{d{\phi _B}}}{{dt}} < 0$ and drops to zero. So according to equation (1), the induced emf will be positive and constant with time i.e., $\varepsilon = + ve$ . Combining all these results the graph depicting the variation of the induced emf with time is sketched below. christus code
