Define induced EMF

Induced emf which is also known as induced electromotive force, electromagnetic induction, and electromotive force induction.

Definition

It can be defined as the generation of a potential difference in a coil due to the changes in the magnetic flux through it. In simpler words, electromotive Force or EMF is said to be induced when the flux linking with a conductor or coil changes.

Ways to induce emf

Electromotive forces can be induced in two different ways –

  • The first way involves the placement of an electric conductor in a magnetic field that is moving.
  • The second way involves the placement of a constantly moving conductor of electricity into a magnetic field that is static in nature.

Applications

The applications of induced emf include are listed below

  • Used in generators
  • Used in galvanometers
  • Used in transformers

It is important to note that all of these devices work on the principle of induced electromotive force.
