The interference of two-dimensional superconducting induced current in vector potential A field

Abstract

If a two-dimensional superconducting mental surface is passed through by two infinite straight magnetic flux which is shielded by superconductivity, and it was supposed that the change rate of flux was not equal to zero at the beginning, which would induce two opposite and equal currents on the two-dimensional superconducting mental surface. In this situation, when the change rate of flux changed to zero, and both magnetic fluxes remain constant, new physical interference effect would appear. In this paper, the interference streamline distribution on two dimensional superconducting mental surface are calculated and simulated. We named the new interference phenomenon L-J effect, it is considered as a two-dimensional A-B effect.
