Motional EMF
Definition
Motional EMF refers to the electromotive force (voltage) induced in a conductor moving through a magnetic field.
Analogy
Imagine you are riding on a roller coaster and suddenly pass through a strong magnetic field. As you move, you feel an electric shock due to motional EMF, similar to how charges experience an induced voltage when moving through a magnetic field.
Related terms
Faraday's Law of Electromagnetic Induction: States that the magnitude of induced EMF is directly proportional to the rate at which magnetic flux changes with time.
Lenz's Law: Describes the direction of induced current in response to changing magnetic fields, opposing their cause.
Magnetic Flux: The measure of magnetic field passing through an area perpendicular to it.
