hearmature is 1,200 revolutions per minute, the resistance of the armature between end plates 1-10 of an ohm and the endplates are so large as to ihave a megligible resisitance ? 136 12. Is there* any difference in their nature betweeneddy currents and the useful current produced by an arma-ture?… … When a dynamo produces current these currents flowaround the armature in such a direction as to magnetizethe armature at right angles to the main field magnets. Aconsideration of Fig. 52 shows this, and if the direction ofcirculation of current in Figs. 45 and 46 be worked out, theresult will be…
