The 3-axis fluxgate magnetometer requires conducting a precise calibration in the magnetic field whose value is determined and which is characterized by the high uniformity of the distribution of the field, especially along the axis of the sensors. The generation of the magnetostatic field characterized by the high uniformity, can be achieved by using the Helmholtz's coils. The requirements of the uniformity of distribution of the magnetic field determine the geometrical measurements of the coils. This paper presents the results of the analysis of the uniformity of distribution of the magnetic field in a specified area of the Helmholtz's coils. This paper also discusses the new method of approximate localization of ferromagnetic objects. The numerical calculations were carried out with MatLab and MathCad package.
