    Abstract: A barium ferrite layer is disposed around an external surface of neck portion of a color cathode ray tube to have a magnetic easy axis radially of the longitudinal axis of the neck portion. An electromagnet is revolved around the layer to magnetically charge it so as to correct static convergence and color purity of three electron beams generated in the color cathode ray tube.
