The electromagnetically induced emf can be classified into two categories:
Statically Induced emf:
In statically induced emf, the coil or the conductor is kept stationary and by increasing or decreasing the current and the flux linked with the coil or conductor is changed.
Dynamically Induced emf:
In Dynamically Induced emf, the magnetic field is kept stationary and the coil or the conductors is rotating and cut across the field.
