Maybe not so but any thoughts on the Phildelphia Experiment, the USS Eldridge and 10 mins of what May or May not have happened?
The Philadelphia Experiment is one of the most bizarre military urban legends ever, and it has persisted as an infamous World War II conspiracy theory

I agree with Victor Meldrew. I don't believe it. The article speculates on the nature of the tests.
"The definite nature of this eerie experiment is yet to be determined. However, the possible tests included experiments like magnetic invisibility, radar invisibility, optical invisibility, or degaussing which made the ship immune to magnetic mines. The experiments were conducted with the intention of retrieving undesirable results"
From Wiki:
The story is considered a hoax: there is a general lack of evidence for the alleged experiment; the person who started the myth—a merchant seaman named Carl Meredith Allen—admitted that he had made up the story and relayed it to author Morris K. Jessup; and the USS Eldridge's deck log and war diary (preserved on microfilm) show that the ship was never in Philadelphia between August and December 1943.[6]
On 15 January 1951, she was transferred under the Mutual Defense Assistance Act to Greece where she served as Leon (D54).[2] Leon was decommissioned on 5 November 1992, and on 11 November 1999, was sold as scrap to the Piraeus-based firm V&J Scrapmetal Trading Ltd.[3]

Magnetic Invisibility? What do they mean by that? Degaussing the hull could reduce magnetic bias and make a ship less likely to attract a magnetic mine. It would not prevent the ship from being
detected magnetically though. During that period of time radar "invisibility" could mean different things. (a) you want to hide your radar by using a frequency the enemy wasn't using or (b) you wanted to obscure your presence by means of chaff or other countermeasures.
From wiki:
Degaussing - The original method of degaussing was to install electromagnetic coils into the ships, known as
coiling. In addition to being able to bias the ship continually, coiling also allowed the bias field to be reversed in the southern hemisphere, where the mines were set to detect "S-pole down" fields. British ships, notably
cruisers and
battleships, were well protected by about 1943.
Installing such special equipment was, however, far too expensive and difficult to service all ships that would need it,
so the navy developed an alternative called wiping, which Goodeve also devised, and
which is now also called deperming.
This procedure dragged a large electrical cable along the side of the ship with a pulse of about 2000 amperes flowing through it. This induced the proper field into the ship in the form of a slight bias.
Degaussing - Wikipedia
Even 2000 Amps through an insulated conductor isn't going to cause an auroral effect, although if it burned through the insulation and shorted or sailors came in to direct electrical contact it would be deadly. Magnetic induction might cause effects in a coil that magnetically coupled with the field. A very high voltage discharge might cause some arcing between bare conductors but not an aurora or eerie green/blue glow, such as a sailor might have witnessed during a convoy in the far North. More likely is the combination of natural phenomenon (Aurora Borialis) mixed with the mystery of scientific trials to become science fiction.

As far as optical invisibility was concerned, it was not possible other than making smoke, keeping below the horizon or using camouflage techniques to break up the distinctive shape.
