Modelling and simulation of cylindrical magnets without core

The aim of this paper is to analyse a proposed mathematical model of cylind rical magnets without core and to present a methodology for it's adjustment . The expressions deduced from Blot and Savart law and the model itself, al lowing the computation of the magnetic field, the vector potential and the magnetic energy, are given. Furthermore a methodology and an algorithm are developed in order to simulate the magnets and coil heads. Some illustrativ e and practical examples are presented. Finally, the validity of the model has been checked out on two known simple configurations of magnets.
