Variational principles of magnetostatics of superconductors. II

Simple examples are provided, where demonstrating the implementation of algorithms formulated by the variational principles of the first part of this paper is quite difficult, because even for the simplest body of practical interest —a loop — solving the problem by classical methods of potential theory is rather difficult. For this reason, presenting the corresponding results requires substantially more space, and obtaining these results can be considered as an independent study.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 103–109, September, 1991.
