Abstract
Purpose. Development of methodology and experimental studies of the layout of the active screening of technogenic power frequency magnetic fields with different control algorithms with a single coil magnetic executive body. Methodology. In the course of mathematical modeling to determine geometrical size of the magnetic coil executive body based on the size of the protected area, and the configuration of the coil magnetic executive body is determined based on the required uniformity of the magnetic field distribution in the protected area. Results. Experimental studies of open, closed and combined systems of active screening of technogenic power frequency magnetic fields with a single coil magnetic executive body. Originality. For the first time experimentally confirmed the possibility of reducing the level of induction of man-made power frequency magnetic fields in a given area 3-5 times with a single coil magnetic executive body.. The possibility of reducing the level of the magnetic field in a limited area of the space by 15-20 times Practical value. On the basis of the calculations the layout of active screening of technogenic power frequency magnetic fields with different control algorithms with a single coil magnetic executive body has been made.
