This paper presents a discussion of the properties and the behavior of an unit magnetic particle as calculated by the DPC (Della Torre, Pinzaglia and Cardelli) model. The general mathematical expressions of the vector field generated by the unit magnetic particle are derived in a special regular parametric coordinates system. It is shown that, in a special case, the DPC model leads to the same results as in the Stoner-Wohlfarth dealing with the physics of an ellipsoidal, single-domain, uniaxial magnetic particle. Some numerical examples for a possible use of the DPC model in the analysis of nanomagnetic samples are presented.
