Armature reaction in a machine is demagnetizing due to _________

Armature reaction in a machine is demagnetizing due to _________ Correct Answer Machine is designed with iron which is slightly saturated

The armature reaction in a DC machine is cross-magnetizing causing distortion in the flux density wave shape and a slight shift in MNA. It also causes demagnetization because a machine is normally designed with iron slightly saturated.
