Question

The production of an electromotive force across an electrical conductor in a changing magnetic field is known as an Electromagnetic induction. Enter 1 for True and 2 for False.

Answer 1

Production of voltage (electromotive force) due to a changing magnetic flux through an area is called electromagnetic induction. This either happens when a conductor is placed in a changing magnetic field (when using AC power source) or when a conductor is constantly moving in a stationary magnetic field or both at the same time.

This phenomenon was discovered by Michael Faraday.
