<p>The object of the research was to separate the eddy-current loss in iron from the loss due to magnetic hysteresis, and determine whether the latter varies or is constant when the max. value of the magnetic flux is kept constant while the form of the wave is varied. By the application of Rossler's formula a separation of the losses may be approximately accomplished by measurements of the total losses at two frequencies and the same flux density. In order to obtain accurate results the following conditions should, as far as possible, be realised: (1) The two frequencies used should be low, and as close together as the accuracy of observation will permit. (2) The form factor of the se
