Work is devoted to original methods of modeling and calculation of static electromagnetic fields and the corresponding parameters in the environment of COMSOL Multiphysics. Calculation of such parameters, as inductance of the coil and capacity of condenser is considered. Approbation of method was produced on the example of circular ring of circular section and spherical condenser with layered dielectric permeability. Advantage of this method is in that calculation can be made not only in the cartesian system, but also in cylindrical or spherical systems of coordinates. The power method of calculation of parameters is offered. Resulting inductance, got through energy of the magnetic field, contains both own and mutual inductance of the electrode system. A resulting capacity, got through energy of the electric field, also contains all capacities from every layers of heterogeneity on separateness. By comparison to the offered method resultant inductance and capacity are calculated on the basis of literary information by a traditional method. Error of calculations by two methods less than 1% talks about adequacy of design. Illustrations of decisions are given in article by means of various surfaces and drawings with explanations
