Magnetic Field around Single Wire Conductor
In 1991 (1), Avramenko found that he could transmit significant amounts of power over a single wire with a very small diameter, without the wire heating up. Even adding a several megaohm resistor did not really diminish the output power, and a thermo milliamp meter was unable to detect the current. Other experimenters have had similar results.
Since I'm travelling, it is hard to perform any experiments, so I've been trying to read a lot to try to figure out what could explain this curious behavior. On Eric Dollard's recommendation, I started reading "Electricity and Matter" by JJ Thomson, and found the following:
And since everyone seems to be saying that Tesla coils produce longitudinal waves, even though I have yet to see anyone prove that definitively, this might be that prove! For if the wave is longitudinal, it will not produce a magnetic force, since its lines of magnetic force are in the direction of propagation (tell me if I'm interpreting this wrong).
Therefore, I would LOVE to know if anyone has performed any of Faraday's basic tests of a magnetic field around a current carrying wire on a single wire transmission line coming off of a Tesla coil:
1. Using a compass to determine the presence and direction of a magnetic field
2. Using iron filings to determine the shape of the magnetic field
If you have performed such experiments, please share your results here! Alternative explanations are also welcome (I'm also toying with the idea that single wire currents could be Maxwell's displacement currents for example).

"We see that it is only the motion of a [line of force] at right angles to itself [= transverse] which produces magnetic force; no such force is produced by the gliding of a [line of force] along its length [= longitudinal]."
