These equations obviously do not apply to the total induction B, but to Bo = B-H: the difference, however, becomes notice- able only at very high magnetomotive forces FIG. 1. Harold Pender (by letter): The effect of iron in distorting the wave-form of current and pressure is of particular importance in determining the energy-loss in small samples of iron by the wattmeter method. In this method of measurement the maxi- mum flux density is usually calculated from the effective pres- sure measured by a voltmeter across the terminals of the mag- netizing winding on the sample; or the induced pressure in a secondary winding on the sample mav be measured, this method eliminating the resistance-drop in the magnetizing winding. In general the maximum flux densitv is proportional to the average value of the induced electromotive force over half a cycle; only in case of a sine wave of induced electromotive force ặTHERFORCE ... 1906] DLICUSSION AT NEW YORK. 695 zero value. That is, the harmonics symmetrical with regard to the electromotive force are noticeable only at the zero point, as a flattening out. The magnetism curve at this point is horizontal, so that the resultant current curve must be horizontal also. This could be expressed by stating that the distortion of the wave of the exciting current is due, not to the energy lost in the iron, but to the magnetic characteristic or the bending of the satura- tion curve, and therefore it is this curve which we should endeavor to construct, the magnetic characteristic as it would be given by a magnetic cycle, in the absence of hysteresis loss. This would probably give approximately the higher harmonics in the ex- citing curve wave. Sometime in 1881 or 1882 Dr. Froehlich noticed that the magnetic characteristic of the dynamo machine could be ap- proximatelyv represented by a parabolic curve. Dr. Kennelly showed, in` 1891*, that the B H curve, or magnetic characteristic of iron, for the higher values, could be expressed by a parabolic curve, an~ equation of the second degree. Using this equation of a parabola for the relation between B and H, there could be found a strictly mathematical curve, about like B in Fig. 5,. which combined with a sine wave representing the hysteresis loss, would fairly closely represent the distorted wave of exciting current. In dealing with hysteresis we have to keep in mind the difference between magnetic hysteresis and the energy lost in the iron. If iron is exposed to an alternating magnetic field, the loss of energy that takes place in the iron, by some form of magnetic *Magnetic Reluctance, by A. E. Kennelly, TRANSACTIONS A. I. E. E.
