A new current dipole model is proposed to estimate magnetic field sources. A set of the current dipoles represents a closed-loop current element, always satisfying current continuity. The target region is filled with the closed-loop current elements to derive a system of equations, then its solution estimates unknown current distribution from given magnetic field data. The generalized vector sampled pattern matching method performs applications of current visualization and coil design in this paper, showing that our model stably yields solutions in spite of row-wise rectangular system of equations.
