My reply was a tongue in cheek wild ass guess, but it only takes 1 1/2 volts applied to a loop of wire to cause it to have a magnetic field. NOT thousands. Didn't you ever play with door bell battery like we used to use to start out models, a piece of wire and a big nail to make a magnet??? Or are you a millennial..
Since Perry and I are well acquainted, he knows I am kidding...
Sorry -- I didn't put down my complete thought process.
Voltages of the sort that we have in our planes would make a magnetic field on the line, but in general if anything shorted
to the lines there'd be smoke -- and there's no path from electronics to lines, anyway.
Which gets back to electrostatics, which also has no mechanism.
So, maybe it's just Evil Malign Forces.
