Numerical Analysis of Hysteresis and Eddy Current Losses in Solid Cylindrical Rods of No. 1010 Steel

A procedure is given which utilizes the digital computer to solve eddy current loss and hysteresis loss problems. The relationship between flux density and magnetic intensity is taken from the actual magnetization curve and major hysteresis loop, thus eliminating the approximations employed in most previous investigations. The nonlinear partial differential equations are replaced by finite difference equations and solved by numerical methods on an IBM 7090 digital computer.
