Armature reaction is demagnetizing in nature due to purely lagging load.

Armature reaction is demagnetizing in nature due to purely lagging load. Correct Answer True

Due to purely lagging load, armature current is in opposite phase with the field magneto-motive force. Armature magneto-motive force produced due to this current will be in the opposite phase with the field flux. It will try to reduce the net magnetic field.
