What is meant by degaussing?
Answer:
Degaussing is the process of decreasing or eliminating an unwanted magnetic field. It is named after Carl Friedrich Gauss, an early researcher in the field of magnetism. Due to magnetic hysteresis it is generally not possible to reduce a magnetic field completely to zero, so degaussing typically induces a very small "known" field referred to as bias.
You could theoretically 'Degauss' a credit card by placing it on one of those magnetic strips on the counter...you can wipe details off the card. You can degauss cassette tapes and videos...but mainly it will apply to ships and naval technology.
We sometimes get asked (and people pay good money for this even though I have told them it is a waste) for non-magnetic metal fittings. They ask us to demagnetise them (even though a slight chink against another piece of metal can remagnetise them again). Pretty useless procedure when the fittings are attached to metal pipes...
Degaussing is Demagnetisation. Needed in some processes to prevent parts from sticking to each other.
i have no clue what it means... but i used to love doing it on all the school computer monitors and then seeing the effect it had on the nearby monitors, lol... how sad i once was :P
The process of eliminating magnetization on a CRT is called degaussing (the unit of measure of magnetic inductive force is the gauss, named for mathematician Karl Friedrich Gauss). Most modern CRTs today include built-in degaussing circuits. Some have a manual switch to activate the circuit, some do it automatically and some offer both as an option. The degaussing circuit uses a coil of wire to neutralize magnetic fields within the CRT.
