Spring Model of Hysteresis Applied to Tape‐Wound Cores

摘要

The theory of the spring model of hysteresis is compared with experiment for a number of magnetic materials. The properties of the spring model as they relate to minor hysteresis loops are summarized. Loops from tape‐wound cores of various materials are compared with these predictions to see if the cores obey the model. It is found that some cores, square orthonol and square Permalloy 80, fit the model quite well. Other cores, round orthonol, supermalloy, and magnesil, deviate considerably from the predictions of the model. It is believed that these cores can be made to obey the model by taking into account an internal self‐generated field which acts on the domain walls in addition to the applied field.
