Concept of statically induced emf: The emf induced in coil or conductors without any relative motion between it and magnetic field is called statically induced emf. When conductor is stationary and flux linking with it changes, the emf induced is known as statically induced emf. e.g. Emf induced in transformer windings. 

Concept of dynamically induced emf: The emf induced in coil or conductors due to relative motion between it and magnetic field, is called dynamically induced emf. When a conductor is moved in the magnetic field produced by fixed poles, it cuts the flux and emf is induced in it. This emf is dynamically induced emf. e.g. Emf induced in generators, alternator.

Statically induced EMF: An EMF induced in a conductor without physical movement of conductor or magnet but by changing magnetic flux is called as statically induced EMF.


Dynamically induced EMF: An EMF induced in a conductor by physical movement of conductor or magnet with respect to magnetic flux is called as dynamically induced EMF.


Transformers, Choke, coupled coil are the examples of statically induced EMF.


Alternators, generators, motor, are the examples of dynamically induced EMF.

Ans: Statically induced emf: The emf induced in coil or conductor when conductor is stationary and flux linked with it changes with respect to time then it is known as statically induced emf.
