WebGalvanometer and coil. Faraday's law is a fundamental relationship which comes from Maxwell's equations. It serves as a succinct summary of the ways a voltage (or emf) may be generated by a changing magnetic environment. The induced emf in a coil is equal to the negative of the rate of change of magnetic flux times the number of turns in the coil. 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. The direction of the electromotive force is given by Lenz's law.An often overlooked fact is that Faraday's law … thorium chemical formula
