Magnetic interaction in superconducting systems modelling

This article describes the effect of ¿magnetic potential well¿ (MPW) that is considered to be an exclusion of the classical Earnshow´s theorem. Two physical effects are described here: the relationship between the minimum potential energy produced by the magnetic interaction and the stability between the static system and the magnetic interaction. Both the theoretical model and the experimental part confirm that the presence of the zero force of the magnetic interaction gives minimum of potential energy and provides the system stability.
