SYSTEM OF COILS FOR VIBRATION MAGNETOMETER Russian patent published in 2016 - IPC G01R33/12 

FIELD: measurement equipment.

SUBSTANCE: system of coils for a vibration magnetometer comprises multi-turn measurement coils and also comprises an additional coil fixed relative to the source of magnetizing field, and the plane of turns of the coil is perpendicular to power lines of the magnetizing field. The additional coil is connected in series with metering coils, in parallel to the additional coils a potentiometer is connected, and the voltage from the system of coils is tapped off between a movable discharge contact of the potentiometer and a free end of the measurement coil.

EFFECT: increased sensitivity of a vibration magnetometer.
