Reduction of magnetic field level in residential old buildings from overhead power lines by means of active screening

Aim. Reduction of the magnetic field induction to the level of modern sanitary standards by means of active screening in residential old buildings which are located near existing typical overhead power lines are considered. Active shielding of the magnetic field inside a single-storey and multi-stor...
