A cathode ray tube includes an electron gun directing electrons towards a faceplate having an electrode biased at screen potential. The electron beam (three beams in a color tube) is magnetically deflected to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. A first pair of electromagnetic coils forward of the tube neck and deflection yoke is biased by a substantially constant current level to further deflect the electron beam. As a result, the electrons are deflected over a greater total angle than is obtained from the magnetic deflection yoke alone. A further pair of electromagnetic coils proximate the faceplate is biased by an oppositely poled substantially constant current level to direct electrons towards the faceplate, thereby to increase the landing angle of the electrons thereon.
