Permanent magnets are widely used in various technical devices. Mathematical models of magnetic fields of permanent magnets are considered to solve the problems of analysis and synthesis of such devices. The paper proposes a third model, based on the use of point sources of a magnetic field in addition to the two known models of uniformly magnetized permanent magnets (current and charge models). Each point source is characterized by a vector magnetic moment. The features of the model for permanent magnets of various shapes are considered. The advantage of the new model is to reduce the computation time of the magnetic field parameters by reducing the dimensionality of the modeling problem.
