e shape of the curves, the e, m. f. increases at first withthe current, due to the increase in magnetization of the field-mag-nets. As the parts of the magnetic circuit, with increase of load,approach saturation, the reactions of the armature and IR dropsbecome of relatively greater importance; the… … Fig. 160.
