Abstract: The successful calibration of Fluxgate magnetic sensors in the rotating mode instead of the fixed mounting mode gives an idea of the difference between the characteristics of the magnetic signals in these two modes. This article examines the properties of magnetic time series. The magnetic signal is investigated with the standard criteria in fixed and rotating mounting modes. The results indicate a fundamental difference between the characteristics of the magnetic signals in two aforementioned modes. In steady state situation, more random features are observed. However, in the rotational installation, the properties are similar to the chaotic models. In fixed mounting mode, there are unwanted oscillations that are reduced by rotating the sensor. Circulation also highlights environmental magnetic perturbations, making them easier to detect. Various experiments were conducted based on the experimental data of the magnetic sensor in different geographical areas. Fixed and rotating execution in the presence and absence of magnetic disturbance confirms the difference in the nature of the time series in the two cases.
