1. degaussing - Noun
2. degaussing - Verb
the process of making a (steel) ship's hull nonmagnetic by producing an opposing magnetic field
Source: WordNetA degaussing circuit using a PTC thermistor is simple, reliable (for its simplicity), and inexpensive. Source: Internet
Initially, major warships and large troopships had a copper degaussing coil fitted around the perimeter of the hull, energized by the ship's electrical system whenever in suspected magnetic-mined waters. Source: Internet
Improved degaussing circuits have auxiliary heating elements to heat the thermistor further (and reduce the final current) or timed relays to disconnect the degaussing circuit entirely after it has operated. Source: Internet
In this field the British, with their large seagoing navy, have had the bulk of world experience, and most anti-mine developments, such as degaussing and the double-L sweep were British inventions. Source: Internet
Many of the boats that sailed to Dunkirk were degaussed in a marathon four-day effort by degaussing stations. Source: Internet
The coil and thermistor are intentionally sized so that the current flow will heat the thermistor to the point that the degaussing coil shuts off in under a second. Source: Internet
