WebApr 8, 2024 · Faraday's Law is conducted to see the way magnetic fields change due to the flow of current in wires. This law was first projected in 1831 by a chemist and physicist “Michael Faraday”. Because of him, the law got its name. Faraday's Law is the outcome of the observations of the three main experiments that he had conducted. 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.
