Abstract

We analyze the features of motion of a superconducting loop in the magnetic field of a dipole (problem of “two magnets” with a fixed center). The force function of such a loop in a constant magnetic field, which makes it possible to determine the intensity of interaction and the equations of motion, is sub-stantiated. The structure and stability of a set of equilibrium states in the “magnetic dipole-superconducting loop” dynamic system is considered. It is shown that the absence of ohmic resistance in the loop changes the type of magnetic forces and leads to the formation of a stable set of equilibrium state in the problem of two magnets.
