Residual voltage is a result of magnetism in the?

Armature winding

Rotor

Stator

Field shoes

Residual voltage is a result of magnetism in the field shoes. In a generator or an electric motor, residual magnetism refers to the magnetic field that remains in the field shoes of the rotor even when the power to the machine is turned off. This residual magnetism helps in starting the generation of electricity or rotation of the motor when power is applied again. Armature winding, rotor, and stator do not directly produce residual voltage in the same way as the field shoes do.
