WebNov 5, 2024 · Faraday’s Law connects the flux of a time-varying magnetic field to an induced voltage (rather than a current). For historical reasons, the induced voltage is also called an induced “electromotive force” (emf), even if it is a voltage and not a force. Faraday’s Law is as follows: (23.1.1) Δ V = − d Φ B d t. where Δ V is the induced ... WebFaraday's law (also known as the Faraday–Lenz law) states that the electromotive force (EMF) is given by the total derivative of the magnetic flux with respect to time t: =, where is the EMF and Φ B is the magnetic flux through a loop of wire.
