Abstract
A deflection yoke for a cathode ray tube comprises a generally tubular core, a first deflection coil assembly including a pair of first deflection coils wound on the core and arranged in symmetrical relationship with each other about the longitudinal axis of the core and operable to deflect electron beams, traveling from an electron gun assembly towards a phosphor-coated screen region, in a horizontal direction, and a second deflection coil assembly generally toroidally wound on the core and operable to deflect the electron beams in a vertical direction. A pair of magnetic members are mounted on the core in opposition to each other and positioned on the imaginary horizontal axis perpendicular to the longitudinal axis of the core while spaced 180.degree. from each other about the longitudinal axis of the core. Each of the magnetic members is constituted by a generally elongated body having a pair of legs protruding from the elongated body which legs are spaced from each other in a vertical direction. A magnetizing member for each magnetic member is also provided for developing predetermined poles in the legs of each of the magnetic members.
