<p>A deflection yoke apparatus comprising pairs of horizontal and vertical deflection coils, a coil separator (13) located between both coils, a deflection core forming a magnetic path for a magnetic flux generated from both deflection coils and two auxiliary coil means (16,17) which are arranged at diametrically opposed positions in a vertical deflection direction outside said deflection core. Said auxiliary coil means comprise coils (18, 19) wound on magnetic rods (20,21) of high magnetic permeability. A horizontal deflection current may be supplied to the auxiliary coil means and a magnetic field generated from said auxiliary coil means reduces an intensity of externally leaking magnetic field which radiates outside said deflection core when a horizontal deflection current is supplied to said horizontal deflection coils. The auxiliary coil means are slantly arranged in engaging relationship with the smaller diameter end of the deflection core. <IMAGE></p> |
