Abstract
This paper discusses the process of magnetization and the eddy-current losses in saturated cylinders subjected to a sinusoidal magnetic field. Maxwell's equations are solved in cylindrical co-ordinates for an assumed magnetization curve B = Bs sign H. This leads to a transcendental equation which is solved by numerical analysis; the results are normalized and given in the form of curves from which losses and power factor can be found easily. Tests made on an experimental core are in agreement with calculated results. Comparisons are made with other theories also.Keywords
