PURPOSE:To prevent the undesired emission of leaked magnetic field, which is leaked from a deflecting yoke of a cathode-ray tube, to the outside. CONSTITUTION:An auxiliary coil 25, which is wound like '8' from an upper horizontal deflecting coil 1A toward a lower horizontal deflecting coil 1B of a deflecting yoke 24 installed in a cathode-ray tube, is provided. This auxiliary coil 25 is connected in series or in parallel to/with a horizontal deflecting coils [1A, 1B] of the deflecting yoke 24 so as to generate the magnetic field 26 opposite to the leakage magnetic field 15 of the deflecting yoke 24. |
