FIELD: technology for protecting biological and physical objects from magnetic influences.
SUBSTANCE: axes of three-component ferro-probe rod magnetic meter are combined with axes of Helmholtz, while semi-elements of differential rod ferro-probes are distances along axes from working volume center, that is why working volume is unified for positioning of effect subject and magnetic meter.
EFFECT: improved precision of detection of magnetic disturbances, due to combination of measurement volume with compensating volume, the latter may be increased.
