Sound does not affect electrons.
Exciting the electrons of an atom does not not create a magnetic "charge" (there is no such thing).
There is some evidence that earthquakes may be associated with fluctuations of the Earth's magnetic field. The fluctuations are very slight (requiring very sensitive instruments to detect them).

A Tesla is equal to 10^4 Gauss, I'm suspect of classes you got edumacated in to not know that. The only thing suspect I would say is your "expertise".edit on 22-3-2011 by Liberterius because: (no reason given)

HAARP transmits high frequency radio. Radio waves don't really have any effect on magnetism.
A Tesla coil might affect compasses near to it but it would also create a lot of radio interference that people would be likely to notice. The FCC doesn't take kindly to that kind of thing.
A 40 ton magnet would affect compasses close enough to it. I don't know how close but call it 1 mile just for fun (I doubt it would be even close to that). It would be pretty easy to locate it, it would be it's own homing device. Everyone's compass would point to it. You could drive around with a compass and find it.

I am in northwest montana, Whitefish to be exact, the time is 5:01pm on march 22 2011 my compass is pointing almost due east about 75 deg. Earlier in the day it was pointing northwest about 320 deg. at 11:21 am

As the sound waves move, this creates a novel way of transporting electrons--and therefore electric signals--from one place to another in a semiconductor.
A powerful surface acoustic wave can transport charge along a quasi-one-dimensional channel defined in a piezoelectric semiconductor in packets confined to the minima of the wave’s electrostatic potential. The interaction between electrons can suppress fluctuation in the number of electrons in a packet, resulting in a current that is proportional to the surface acoustic wave (SAW) frequency. This effect has been observed experimentally and is presently being considered as a possible route towards a standard of electric current. Here we present further study of this acoustic charge transport. The main finding is that a weak counterpropagating SAW beam can be used to improve the precision of the current delivered by the device.

I have bachelors degrees in Pure Mathematics (theoretical as Brits call it) and Physics, no minors, both majors.
If you don't know what a Tesla is I don't see why I should continue this conversation or take anything you have to say seriously. Is that plain enough?
Again you are the turd or firth person to say I am slinging, or doing anything, aside from being 100% forthright and honest about what is the truth. If my facts do not fit your mis-information, trust me, it is not I who am "slinging" anything. Go and play now child.

You're right, I misspoke. In piezoelectric materials vibrations can produce an electrical current, movement of electrons. In my defense, it isn't really "exciting" the electrons.
Oh, I see kdog1982 edited his post to change it from sound to radio. In that case I was right. The piezoelectric effect requires mechanical motion, it is not induced by electromagnetic radiation.
