Here is your answer ....
ELECTRIC MOTOR
Electric motor is a rotating device that converts electrical energy into mechanical energy. Electric motor is used as an important component in electric fans, refrigerators, mixers, washing machines, computers, MP3 player etc .
PRINCIPLE :-
Electric motor is based on fact the current carrying conductor placed perpendicular to the magnetic field experiences a force .
ELECTRIC GENERATOR
An electric device used to convert mechanical energy (kinetic energy) into electric energy (electricity ) is called electric generator .
PRINCIPAL :- Electric generator works on the principle of electromagnetic induction. When the coil of electric generator rotates in a magnetic field , induced current flows in the circuit connected with the coil.
Types of electric generator :-
☆ AC generator : AC generator converts mechanical energy into electrical energy in the form of alternating current or AC .
☆ DC generator :DC generator converts mechanical energy into electrical energy in the form of direct current or DC.
