In this paper we discuss some properties of the radial vector model (RVM) proposed as a three-dimensional extension of the classical scalar Preisach model (CSPM). In particular, we prove that the irreversible model of magnetization of the RVM is consistent with the conservation of magnetic energy and with the second law of thermodynamics. The model continues to have these properties even when a reversible component of magnetization is added to the magnetization.
