    摘要: Series connected first to fourth reactor coils (12-15) are wound on a core (33) and connected in series with a horizontal deflection coil (11). A coil (22) is also wound on the core and connected in series with a vertical deflection coil. The core (33) is provided with two permanent magnets (34,35) and magnetic bias is applied to the first to fourth reactor coils. A total inductance of first to fourth reactor coils (12-15) is controlled by a vertical deflection current passing through the coil and thereby, a correction amount of an amplitude of a horizontal deflection current is changed.
