lost as heat, and a portion re-mains in the iron as energy ofmagnetization; and no experi-mental method has been devisedfor determining the second andthird portions of work separ-ately.

The total work spent on the iron isgiven by the value of the integral abV extended over the whole cycle; but the value of jx-dy extendedover the whole cycle is the area enclosed by the Si and dt curve.Therefore,…
