If you can look at what load is fed through those particular wires, you might be able to turn it off as an experiment. If there is no load on the wires, there will be no current or magnetic field. If the noise is still present, you could conclude that it's electrostatic.=20

** HUH ???YOU need to say how the HELL it demonstrates YOUR MAD CLAIM first.
** Fender Strats are the VERY WORST environmental hum field receivers ever sold !!!!The stupid, plastic covered, single coil PUs are not even ES shielded !!!
Most of the wiring is NOT shielded

They got you to help them. Not so dumb are they?
You should be able to know what the field is first. Take your equipment common and attach a wire to a piece of aluminum window screen or just plain alauminum metal. Wave it around with the guitar fixed. Then take a fairly large piece of steel and wave it around. If the first method made changes then thats a electrostatic field, and the second magnetic and partially electrostatic.

As others have noted, this problem may not be helped by a Faraday cage, which only provides electrostatic shielding. But it should be easy enough to test this for yourself, by wrapping your guitar in aluminum foil. (You should first wrap it in plastic so the foil doesn't contact the strings.) Then ground the foil... presto! A mini-Faraday cage!
Don't worry about the fact that Faraday cages usually use copper mesh. The difference here will be trivial, except to your wallet.
I'll be surprised if it solves your problem, but at least you'll know quickly and cheaply. And if it doesn't, I don't have any tricks to offer.... I've also had plenty of hum problems from alleged humbucker pickups. Which is pretty annoying considering that they cost more, sound worse, and have lower output than ordinary "hot" pickups.

Two corrections:
1) a faraday cage shields agaist electrostatic and magnetic fields, in case of an AC field.2) a faraday cage does not need to be grounded.

Thanks for the definition. In this real world situation, you have an imperfect cage, and you have things inside coupled to the outside.

A Hoffmann 14-gauge formed-and-welded steel electrical enclosure is a pretty substantial hunk of metal, and won't dependably attenuate a 60 Hz magnetic field by 2:1, a mere 6 dB. And the bigger the box, the worse the shielding.

You're wasting your time !
I do know a guy who built a huge Faraday cage in Mark Knopler's studio in London btw.

You need a different guitar.

In my day they were called "screen rooms". We had one at Motorola SPD that was 10' X 10' X 10', 2" X 6" studs, wire mesh on both surfaces.

There was something pretty similar to that at Kelvin Hughes radar. Interesting place to work for a while.
Graham
Almost. The currents induced in the conductor take energy off the field and thus attenuate it.
