A method to localize a magnetized object from the readings of simple array of magnetometers that is selected to the advantage of magnetic field measurement is applied. In the method the dipole field curve is fit to the readings by weighted least squares, where the weight function that is proportional is applied to the sixth power of the distance between the assumed location of the object and the point for measurement to ensure convergence of the iteration. By an experiment using a ship's magnetic model, it was ascertained that the convergence could be ensured if the initially approximated location is taken farther than the real one.
