A compact ferromagnetic object placed in the earthly magnetic field causes disturbance of this field. This disturbance is associated with magnetization of the object. Ferromagnetic objects have induced and can also have permanent magnetization. In methods of locating and identifying ferromagnetic objects usually is using the model of the dipol moment. Determination of the position and values of the extremes of the magnetic field of the object allows to estimate parameters of the object [3]. This paper presents results of the analysis of positions and values of extremes of the object's magnetic field and the method allows to locate and to identify of objects. The numerical calculations have been made on the basis of MathCAD and Opera 3D.
