The accuracy of potential field restoration using the Neumann problem.
Abstract
The accuracy of potential field restoration using the boundary Neumann problem for the Laplace equation has been studied. The restored field coincides well with the true one provided there are no sources of perturbation around the area of calculation in the distance of the order of the area itself. The disbalance of the magnetic fluxes is negligible. The true potential field significantly differs from the restored one if there exist some misaccounted sources of the field in the vicinity of the area. The error of the field restoration depends upon the distance between the opposite charges in the group of perturbation, on the distance between the group and the boundary of the area and on the value of the changes.
