Abstract: 1. Degaussing apparatus for a television picture tube adapted to be energized periodically by alternating current of magnitude which initially is appreciable and which diminishes effectively to zero comprising in combination: A PAIR OF SADDLE TYPE COILS MOUNTED RESPECTIVELY ON OPPOSITE SIDES OF THE CONICAL PORTION OF SAID TUBE, EACH OF SAID COILS HAVING TWO SIDE CONDUCTOR GROUPS EXTENDING GENERALLY LONGITUDINALLY OF SAID TUBE ALONG AND FROM THE LARGE TO THE SMALL END OF SAID CONICAL TUBE PORTION, SIDE CONDUCTOR GROUPS BEING CONNECTED BY END TURNS RESPECTIVELY AT THE LARGE AND SMALL ENDS OF SAID CONICAL TUBE PORTION; AND MEANS CONNECTING SAID COILS TO SAID SOURCE OF ALTERNATING CURRENT IN A MANNER TO PRODUCE AN ALTERNATING MAGNETIC FIELD WITHIN SAID PICTURE TUBE.
