Abstract
It is shown that when performing surgical operations to remove foreign metal particles from the human body, it is advisable to use metal detectors of various types: flux-gate detectors for localizing ferromagnetic particles, eddy current detectors for localizing non-ferromagnetic metal particles. The sensitivity of medical equipment must be sufficient to detect small ferromagnetic fragments and particles from a distance of at least 10 mm. The feasibility of preliminary magnetization of the search area with a strong permanent magnet is shown. Methods for setting up metal detectors are given. The need to minimize extraneous electromagnetic fields in the operating room is shown.
