A rotational vector preisach model for unoriented media

Heretofore, vector Preisach models have consisted of angularly distributed scalar models. We postulate adding rotational capability to the binary response of the Preisach elements to obtain vector behavior using a single density function.

Description
Summary:Heretofore, vector Preisach models have consisted of angularly distributed scalar models. We postulate adding rotational capability to the binary response of the Preisach elements to obtain vector behavior using a single density function. A rotating field H divides the Preisach density function, which is obtained from scalar measurements, into regions associated with magnetization directions dependent on the applied field history. The magnetizations of elements with h*α‖H‖ (1
