SUMMARY
The discussion centers on the behavior of shielding currents in a superconductor ring, specifically addressing the directionality of the outer and inner wall currents in the presence of an applied magnetic field. The outer wall current is negative while the inner wall current is positive, indicating they flow in opposite directions. The confusion arises from the relationship between the shielding current and the magnetic field, clarified by the realization that the magnetic field is not continuous but rather a trapped field. This understanding resolves the initial misconceptions regarding the equations rotB = μ*j_s and the nature of the currents.
