The article analyzes a nature of forces of interaction between a magnetic field and current-containing closed-loop perfect conducting circuits having a zero ohmic resistance. It is shown that currently the development of superconducting technologies provides for technical feasibility of implementing the electromechanical devices of this type. An expression is derived for a force function of a perfect conducting circuit in an external magnetic field which differs from a known one [1] by an additional term. The distinction is defined by a property of ohmic resistanceless closed-loop circuits to maintain constant a total magnetic flux and hence to retain induction of continuous induced currents in the circuits. Examples show specific features of force interaction between such circuits and a magnetic field.
