FIELD: radio measurements.
SUBSTANCE: invention relates to the field of radio measurements. The fluxgate magnetometric sensor contains a magnetic circuit, as well as cores based on a flat magnetic film made of an amorphous ferromagnetic alloy, an excitation amplifier, excitation windings, two receiving oscillatory circuits with measuring windings and capacitors, current amplifiers switched on in the voltage follower mode, a negative feedback winding, a resistor negative feedback, constant current amplifier in the feedback loop.
EFFECT: creation of a fluxgate magnetometric sensor, which has a low level of intrinsic noise, the ability to operate in high-frequency ranges, when powered by low-voltage current sources.
