In the design of dynamos allowance must be madefor this… … Fig. 19. In most machines there are two effects of the cur-rent in the armature conductors. Referring to Fig. 19,the direction of the field magnetization is represented bythe darts on the poles, and the two effects of armaturecurrent by the darts on the armature, showing the direc-tion of the lines…
