FIELD: medical engineering. SUBSTANCE: device being designed as ferromagnetic probe has handle, casing made from nonmagnetic material and sensitive members being cores and windings connected to electrical measuring instruments. The device also has Permalloy compensation core annealed in vacuum and mounted in bushing made from nonmagnetic material along the longitudinal axis of the handle. The bushing is mounted in the threaded canal of the handle to enable the compensation core to move towards one of core ends in perpendicular direction relative to the plane the sensitive members are spaced. EFFECT: improved functional results. 1 dwg
