ABSTRACT:
Shielding for openings of shielded housings, particularly monitors, has a frame of soft-magnetic material arranged in front of the opening, an electrical coil whose current, controlled by magnetic field sensors, compensates penetrating noise fields in a direction substantially normal to the plane of the opening, with the turns of the coil being located at the inside of the frame.
