RCA 73,572 ABSTRACT OF THE DISCLOSURE To provide static convergence correction motion to the outer beam of three in-line electron beams of a color cathode ray tube, a magnetized sphere is located adjacent each outer beam. Each sphere is magnetized across a diameter to produce, for example, a two-pole magnetic field for providing the correction motion. The two-poles are separated along a polar axis. Each sphere is located in a housing which permits rotation of the polar axis of the sphere into alignment with the longitudinal axis of the cathode ray tube and permits rotation of the polar axis out of longitudinal alignment in both horizontal and vertical planes.
