The evaluation of current distributions in thick superconductors from fieldprofiles near the sample surface is investigated theoretically. A simple modelof a cylindrical sample, in which only circular currents are flowing, reducesthe inversion to a linear least squares problem, which is analyzed by singularvalue decomposition. Without additional assumptions about the currentdistribution (e.g. constant current over the sample thickness), the conditionof the problem is very bad, leading to unrealistic results. However, anyadditional assumption strongly influences the solution and thus renders thesolutions again questionable. These difficulties are unfortunately inherent tothe inverse Biot-Savart problem in thick superconductors and cannot be avoidedby any models or algorithms
