Abstract
A deflection yoke has an induction coil wrapped about its ferrite core at an angle of from 0 to 70 degrees from the horizontal axis of the deflection yoke to supply current to a leakage magnetic-field canceling coil also mounted to the deflection yoke for attenuating a leakage magnetic field produced from the front, rear and side of a cathode ray tube within the deflection yoke without using a separate circular core. This improves the operation and simplifies the production of the deflection yoke as compared to deflection yokes having the leakage magnetic-field canceling coil serially connected to the horizontal deflection coil or using a separate circular core.
