Electromagnetic induction includes an induced electromotive force associated with a changing magnetic field or motion of a conductor in a magnetic field. Faraday's law of induction and motional electromotive force specify the relevant contributions.
Changing the magnetic flux through a long solenoid produces an exterior azimuthal electric field by Faraday's law of induction. A charge whose displacement is negligible during the switching receives mechanical momentumThe result assumes the usual quasistatic field approximation and neglects the particle's displacement while the pulse acts. It describes an electromagnetic induction effect, distinct from the static Aharonov-Bohm effect.
Mutual induction is electromagnetic induction in one electrical circuit associated with a changing electric current in another. In a fixed linear arrangement, mutual inductance quantifies the coupling.

Electromagnetic induction is a physical phenomenon in which a changing magnetic field within a closed loop induces an electromotive force (EMF) or voltage in that loop. This principle is fundamental to much of modern electrical engineering and forms the basis for many technologies, including generators, transformers, and inductors.
