Why is the Magnetic Neutral Axis (MNA) shifted forward in a DC Generator but backward in a DC Motor? (A) Due to the difference in the direction of rotation (B) Due to the direction of armature current relative to the rotation (C) Because generators use carbon brushes and motors use copper (D) Due to different types of core laminations
