llproduce a certain magnetizing effect upon the armature core.This magnetizing effect can best be shown by connecting theterminals of the machine to some source of e.m.f. in such away that the current in the armature will be in the samedirection as though it was produced by the induced e.m.f.(When… … Fig. 143 to the armature current alone is shown in Fig. 143. It isseen that this field is at right angles to the field of themachine. In actual operation the magnetizing effect of thearmature current and thefield current are bothpresent at the same timeand the resultant field isa combination of the…
