Webb10 apr. 2024 · EMF = - N * dΦ / dt. Where, N is the number of turns of the loop. dΦ / dt is the rate of change of flux. t is the time. Φ is the magnetic flux. Lenz's law states that the polarity of induced emf produces a current that opposes the change in flux that produced it. Magnetic flux is defined as the product of magnetic field and area of the loop ... Webb7 juli 2016 · Working hand-in-hand with Faraday’s Law is Lenz’s Law, which states that the polarity of the induced EMF is such that it produces a current whose magnetic field opposes the change which produces it.
