the total energy drawn from themains (neglecting that dissipated due toresistance), a half goes to increase the storeof magnetic energy and a half is convertedinto mechanical energy. It must not be for-gotten, however, that this result depends ontheassumptionoflinearmagnetisationcurves.If it be… … 30. The Lifting Power of an Electromagnet 75 be withdrawn from the stored magnetic energy. In Fig. 66 OD and OB arethe magnetisation curves before and after the operation. The magneticenergy has decreased from OED to OCB, that converted into mechanicalenergy being represented by the triangle OBD,…
