degauss

[dē′gau̇s]
(electronics)
To remove, erase, or clear information from a magnetic tape, disk, drum, or core.
(electromagnetism)
To neutralize (demagnetize) a magnetic field of, for example, a ship hull or television tube; a direct current of the correct value is sent through a cable around the ship hull; a current-carrying coil is brought up to and then removed from the television tube. Also known as deperm.

degauss

To remove unwanted magnetism from a monitor or the read/write head in a disk or tape drive. Some monitors have a built-in degaussing function that can be activated by the user. See gauss and bulk eraser.

A statement by the Navy said: "With reductions in the number and weight of cables, HTS degaussing systems projected for the LPD-17, LCS, CG(X), DDG-1000, and CVN-21 classes of ship will show an estimated 50%-80% reduction in total system weight and a reduced total ownership cost compared to the current system.
Because the HTS cables carry a much greater current density than copper, there is a potential 80 percent weight reduction over current copper-cable degaussing systems.
