WebFeb 28, 2024 · Lenz’s Law can be demonstrated as per the formula of Faraday’s law. In the formula, the given negative sign gives Lenz’s law. The expression is as followed: Emf = − N (ΔϕΔt) Here, Emf = induced voltage (or called, electromotive force) N = Number of loops Δϕ = Change in magnetic flux Δt = Change in time Read More: WebOnce it gets going, Lenz' law says it will create a back EMF that will oppose the original. The sum of that back EMF and the original lead to a lower total voltage to the motor once it reaches speed, and less current flowing through the motor, and then the lights get bright again. 3 comments.
