Also known as induction, EM induction

production of voltage by a varying magnetic field

AI overview

Electromagnetic induction is the process where a changing magnetic field creates an electrical voltage in a nearby conductor. This discovery matters because it's the fundamental principle behind electric generators, transformers, and many other technologies that power modern life.

Alternating electric current flows through the solenoid on the left, producing a changing magnetic field. This field causes, by electromagnetic induction, an electric current to flow in the wire loop on the right.

Electromagnetic induction or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field.
