The production of a potential difference (voltage) when a conductor, such as a wire, is moved through a magnetic field or exposed to a varying magnetic field. ... A current through any conductor creates a circular magnetic field around the conductor due to Ampere’s law. WebDefinition: Electromagnetic Induction. When a loop of conducting wire is exposed to a changing magnetic field, a current will be induced in the wire. There are many ways for a wire to experience a changing magnetic field. Consider again our bar magnet and wire loop, this time with field lines omitted for clarity.

WebAnswer: Provided the wire moves in the right direction, electrons move in the wire so an electromotive force (emf) is induced.
