Degaussing was routinely done to warships as part of scheduled maintenance.
Mines and torpedoes of the era used the magnetic field of the hull to target and detonate. Periodic degaussing reduced the mag field signature.
Current shipbuilding techniques use different steel alloys that minimize the affect or have some degaussing equipment built in. Also, modern weaponry
uses other methods than magnetic field detection.
According to the descriptions of the wiring and generators used in the alleged 'Philadelphia Experiment' a standard periodic degaussing is what
occured. Occasionally on the History Channel there is a show that talks about degaussing and the film clips are exactly like the description of the
'Experiment'.
