In most commercial equipment the current surge to the degaussing coil is regulated by a simple PTC thermistor device, which initially has a low resistance but quickly changes to a high resistance due to the heating effect of the current flow.

They are also used in the degaussing circuits of many CRT monitors and televisions where the degaussing coil only has to be connected in series with an appropriately chosen thermistor; a particular advantage is that the current decrease is smooth, producing optimum degausing effect.

If the degaussing circuit in the TV is indeed busted you can actually get degaussing guns-you used to be able to rent them from stores that sold TV's-but since almost all TV's have their own built-in degaussing coils, that probably won't get you anywhere.

Kurt-Caesar Hoffmann served as the ship's captain from June to September 1939 . In late 1939, a degaussing coil was installed on the ship's hull . " K�nigsberg " returned to active duty in March 1940, when she was assigned to the invasion force for the attack on Norway.

On 15 November 1938, Captain Aritomo GotM assumed command of the ship . " Mutsu " was placed in reserve from 15 December 1938 to 15 November 1939 . She was refitted in early 1941 in preparation for war; as part of this work, she was fitted with external degaussing coils and additional armor for her barbettes.

Most color CRT displays, i . e . television sets and computer monitors, each have a built-in degaussing ( demagnetizing ) circuit, the primary component of which is a degaussing coil which is mounted around the perimeter of the CRT face inside the deform ( bend ) the shadow mask, causing a permanent color distortion on the display which looks very similar to a magnetization effect.
