Abstract :
Although scalar Preisach models have been increasingly accurate and efficient in describing material behavior, vector models, necessary to quantize complex magnetizing processes, are not as well developed. This paper presents a coupled vector model where the coupling is performed by a set of selection rules, after which the individual components can be calculated independently, This model reduces to a scalar model under appropriate conditions and the identification of its parameters is very straightforward
