Johann Carl Friedrich Gauss (German; 30 April 1777 – 23 February 1855) Mathematician and scientist of profound genius who contributed significantly to many fields; including number theory, analysis, differential geometry, geodesy, magnetism, astronomy and optics. In electrical engineering the gauss, abbreviated as G, is a unit of magnetic flux density or magnetic induction. Many television sets that use a large cathode ray tube employ an automatic degaussing electromagnet. This produces a noticeable but brief hum when these televisions are first turned on, and is designed to prevent image distortion which would be caused by residual magnetism surrounding the picture tube.
