Faraday’s law of electromagnetic induction, named after the pioneering physicist Michael Faraday, defines how a changing magnetic field affects the induced electromotive force (EMF) in a closed circuit. Simply said, it demonstrates how the motion of a magnet or a changing magnetic field may produce an electric current. To comprehend the core of Faraday’s law, consider moving a magnet toward or away from a coil of wire. As the magnet approaches the coil, the magnetic field within it changes, causing an electric current to flow through the wire. Similarly, moving the magnet away from the coil or altering the magnetic field strength causes a current to flow in the opposite direction. This stunningly simple yet deep notion is the foundation of Faraday’s law.
