Реферат: ABSTRACT MAGNETIC SHUNT FOR DEFLECTION YORES Apparatus for reducing net distributed magnetic radiation in front of a cathode ray apparatus screen. In such cathode ray apparatus a deflection coil is provided having axially aligned and circumferentially aligned wire segments, relative to the central axis thereof, producing a distributed magnetic field in front of the screen which is undesirable. The invention provides a magnetic shunt: disposed between the deflection coil and the screen, the shunt comprising a magnetically permeable material having its configuration and position relative to the coil optimized to maximize cancellation of the net distributed magnetic field at a selected point in space in front of said coil, so as to provide optimized overall magnetic field reduction through the action of the shunt.
