COMPLEMENTARITY BETWEEN THE ENERGY RESULTS OF H AND E FORMULATIONS INEDDY-CURRENT PROBLEMS

There are two opposite opinions on the particular question whether or not the bilateral energy bounds can be established in eddy-current pro blems. The paper is a contribution to this discussion. The authors wil l show that with the variational process previously proposed, the cons traints imposed on the variations of the field quantities generally ca nnot be applied in the numerical calculations. The authors also try to give a possible explanation for the phenomenon of 'complementarity' b etween the energy results obtained by H-oriented and by E-oriented for mulations.
