Abstract: Article is devoted to questions of development and use of active highly sensitive induction sensors in measuring systems of geodynamic monitoring on the basis of geoelectric low-frequency methods. The analysis of options of technical realization of the active induction sensor for geomagnetic researches for the purpose of increase in metrological parameters is carried out. It was found that structurally improve sensor sensitivity can be due to the use of sectioning. At the same time natural resonance frequency of the sensor displaces to the area of the upper frequencies, improving metrological parameters of the magnetometer in general. Assessment of level of a magnetic signal at geodynamic control with use of low-frequency electroprospecting methods is given. It is noted that to achieve the goals inductive sensor must be designed in conjunction with the preamplifier and be connected to a highway filtration through a communication line. Results of the pilot studies directed to measurements magnetic components when using bipolar installation with use of the experimental magnetometer designed taking into account the methods stated in this article are given.
