摘要:
A deflection yoke having cancelling loop coils for reducing undesired portions of a horizontal deflection magnetic field generated by a deflection yoke body without mislanding. The cancelling loop coils generate a cancelling magnetic field which includes two peaks in a front region and a rear region of the deflection yoke body in which the undesired field portions exist, respectively. The peaks are opposite in direction to the horizontal magnetic field generated by the deflection yoke body, respectively, with same ratio to the deflection magnetic field, so that the undesired magnetic field portions are under-corrected in the front portion and over-corrected in the rear portion.
