Particulars
Statically induced emf
Dynamically induced emf
Movement of coil or magnet
Neither coil nor magnet moves
Either coil moves or magnet moves.
Current through coil of electromagnet
Must vary with respect to time
Can remain constant.
Expression for induced voltage
e = - L(di/dt) or -N(dФ/dt) 
e = Blv sinϴ
Applications
Transformer
DC generators, Back emf in DC motors, Induction motors.
Types
i) Self-induced emf ii) Mutual-induced emf
No sub-types

Statically induced emf
Dynamically induced emf
Emf is induced without any relative motion between conductor and magnetic field.
Emf is induced due to relative motion between conductor and magnetic field.
Emf is induced when changing magnetic field links with a conductor.
Emf is induced when conductor cuts the magnetic field due to relative motion between them.
Direction of statically induced emf is given by Lenz’s law.
Direction of dynamically induced emf is given by Fleming’s Right hand rule.
Two types: Self-induced emf Mutually induced emf
No such further classification
e.g. emf induced in transformer windings
e.g emf induced in Generator, Alternator armature windings
