PURPOSE:To reduce unwanted radiation coming from a deflecting yoke device, by furthermore mounting cancel coils which generates a magnetic field opposite to the needless radiation leaking as one part of the horizontal deflecting magnetic field generated by horizontal deflecting coils. CONSTITUTION:A pair of saddle-shaped horizontal deflecting coils 2, 3 and toroidal vertical deflecting coils 4, 5 are wound on the inner plane and the periphery of a circular core 1, so as to compose a deflecting yoke 7 used in a television receiver or the like. Furthermore, cancel coils 8, 9 are mounted so that they are positioned in loop shapes on the X axis of the deflecting yoke 7 and wound/disposed apparently in toroidal shapes toward the core 1. And they are connected in series with the horizontal deflecting coils 2, 3 in order to generate a magnetic field opposite to the needless rediation which leaks outside from the core 1 as one part of the horizontal magnetic field. Therefore malfunctions, image disturbance, and the like in other devices approximating the deflecting yoke 7 can be effectively suppressed. |
