field winding

(Electrical Engineering) the insulated current-carrying coils on a field magnet that produce the magnetic field intensity required to set up the electrical excitation in a generator or motor

If power supply connected with magnetic field winding of DC Machine and rotor of the machine is turned by an external source of mechanical power, then a voltage will be induced in conductor of rotor, this voltage will be rectified in DC output by using machine's commutator, a magnetic field will produce around it which will disturb the original magnetic field from the poles this distortion of flux in DC machine is called Armature Reaction.
