Loss Due to Magnetic Hysteresis in Silicon-Steel Sheets

Abstract

WE have determined magnetic hysteresis loops by the ring-ballistic method for three different sheets of silicon-steel in an extensive range of values of magnetic flux-density B_max. (B_max, is the flux-density corresponding to the cusp of the loop). From these loops we have derived the energy loss W, in ergs per cubic centimetre per cycle for different values of Umax., and by plotting those values against the corresponding values of B_max, we obtained the accompanying curves for three sheets of steel.
