Shame on us!!!!

So right after class it all swept back to me.

We must remember our right hand rules. An electric current through a wire evokes a circular MAGNETIC field around that wire according to the right hand rule. If we can capturee that magnetic field by coiling wires around IT, then we can turn that back into an electric field/current/voltage. Aha!!

So with sore fingers and knuckles, I give you:
The new pervasive coil for 2007: Take an eyebolt, hack off the bolt, spread the eye so it can be slipped over the hot lead of our AC line:

Hammer the eyebolt back together to make the best closed conductor of a circular magnetic field (this would be better with a more ferrous material):

Wrap as much wire around it as I have time for:

And Voila!! An evoked AC potential of just under a millivolt. More wire windings would increase the evoked AC. A more ferrous core would probably help. Attaching a megohm resistor didn't increase the voltage by that much, because I suspect my volt meter has a small load in it anyway:

This single new cable is laying just in front of the PervLab/Classroom projector. Be nice and share, and get ready to get sore knuckles winding wire and bending eye-bolts.
