In order to continue works on creation of the plasma trap with levitating magnetic coils the analytical function of the potential energy U(x,θ) of the system of two coaxial superconducting rings (and the upper ring is fixed at that), which trapped given fluxes of the same sign, in the homogeneous gravity field versus the coordinate x of the free ring and the deflection angle θ of its axis from the vertical has been obtained under approximation of thin rings. For manufactured HTSC rings, which trapped fluxes of the same sign, with the help of calculations of the dependence U(x,θ) in Mathcad system, such values of magnetic fluxes trapped by rings have been obtained under which equilibrium states of the free ring in the field of the fixed ring, stable to the shift of the levitating ring plane along the common axis and to the deflection of its axis from the vertical, exist. The existence of the determined by calculations equilibrium state for HTSC rings under trapped fluxes of the same sign, stable to the vertical shifts of the levitating ring and to the deflection of its axis from the vertical, has been proved experimentally.
