体。 A ring-shaped internal magnet is fixed and placed at the focal point of the electron beam generated by the first lens of the electron gun inside the valve neck, and a ring-shaped external magnet is variably placed close to the internal magnet outside the valve neck. The electron beam focusing condition is changed by changing the relative position of the external magnet with respect to the internal magnet to the beam direction and a direction perpendicular to the beam or a direction rotating around the beam. A focusing magnet structure for a cathode ray tube characterized by:
