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