What is the voltage created when movement occurs in a magnetic field?

The phenomenon of voltage being generated as a result of movement within a magnetic field is described as induced voltage. This occurs due to electromagnetic induction, where a changing magnetic field induces an electromotive force (emf) in a conductor. When a conductor, such as a wire, moves through a magnetic field or when the magnetic field around a stationary conductor changes, it disrupts the existing magnetic lines of force, creating a voltage across the conductor.

This principle is foundational in applications like electric generators, where mechanical energy is converted into electrical energy. Therefore, the term "induced voltage" specifically refers to this generation of voltage through movement or change in a magnetic environment.
