f conductor in centimeters,and (B = flux density of magnetic field in gausses. Irrespective of the multipolarity of the field magnets or ofthe method of armature winding, the force actions betweenthe magnetic field and all the currents in the inductors willconspire to produce rotation in one… … Consider a single armature conductor, Fig. 127, to carrya current flowing away from the observer. The Unes offorce which surround the con-ductor due to the current in itwill have a clockwise direction.Thus, to the right of the con-ductor these lines will have thesame direction as the lines offorce…
