DC Motor

Electric motors are devices that convert electrical energy into kinetic energy of rotation, by the flow of electric currents through magnetic fields.The principle that a current flowing through a conductor which is placed in a magnetic field results in a mechanical effect, that is the conductor experiences a force, is exploited in electric motors.DC motors are everywhere! In a house, almost every mechanical movement that you see around you is caused by an DC (direct current) motor.
