The Preisach model is utilized to model Barkhausen noise in magnetic core materials. Barkhausen noise is generated each time the magnetization goes through a sudden change at a local site in the core material. In this article we examine the relationship between the shape of magnetization hysteresis loops to details of Barkhausen noise levels or excitations. On the basis of hysteresis loops alone it may be possible to profile the noise spectrum of a magnetic core.
