ABSTRACT:
A plurality of permanent magnets are usually disposed within a cathode ray tube for correcting the magnetic field causing misconvergence or raster distortion of beams travelling within a cathode ray tube. Since the magnets of plate shape are magnetized in the thickness direction thereof being reversed at both the ends thereof along the longitudinal direction thereof, it is possible to effectively distribute magnetic field generated by the permanent magnets within the cathode ray tube without increasing the thickness of the magnets.
