The invention relates to super-sensitive bio-magnetometry at presence of external electromagnetic interferences. A device for passive compensation of interferences at input of biomagnetic measuring device includes compensation elements and means for displacement of those as part of units for mounting, displacement and fixation. In the main embodiment three closed conducting circuits are used, those are orthogonally oriented in space, moved independently up-down with respect to measuring device or its input antenna. The circuits are fixed in positions at coming to minimum of amplitude of external noises by respective projection of field. Variants with cooling the measuring device and/or circuits are proposed, with placement of circuits in cryostat and making those of superconductors. |
