FIELD: measuring equipment.
SUBSTANCE: invention relates to the field of measuring equipment, namely to devices for measuring alternating magnetic fields, in particular to devices for high-precision measuring spatial components of induction vector of the magnetic field using induction sensors. The three-axis induction magnetometer with self-calibration consists of six identical induction sensors with ferrite rod cores. The sensors are connected in series in pairs and located along three mutually perpendicular axes with central geometric symmetry, the center of which coincides with magnetic center of the magnetometer. The internal three-component measure of magnetic induction is additionally introduced, which consists of dielectric cube, the center of which is combined with magnetometer center, with cube edges parallel to its axes, with inductance coils with at least one turn applied on each cube face around the induction sensor axis.
EFFECT: increased accuracy, stability and reliability of operation of the three-axis induction magnetometer.
