Copper is just a poormans gold.

Those other three chunks of aluminum will do their jobs without protesting now.

Skip to 1:50 or so to get straight to molten goodness then probably about 2:40 to give yourself enough lead-up time for the awesome finish.
Would this take more or less energy than simply passing a current through the aluminium (guessing possibly even) or through conventional means (guessing a lot more) ?
Aluminum is a pretty good conductor of electricity, not quite as good as copper but same ballpark. I don't see the copper coil showing much evidence of heating up, which makes me guess the aluminum wouldn't either.
Tungsten is a pretty good conductor as well; but what makes a tungsten light bulb work is that it's a narrow filament trying to conduct way too much electricity.
The copper coil is inducing a very strong electromagnetic current through the Aluminum. The induction is causing the Aluminum to heat up.
Don't you all find it interesting that the phase of the last turn on the induction coil has been inverted? WELL, DON"T YOU????
Now I'm sad, because my high school physics class didn't go anywhere near this kind of thing :-(
OW - you seem to want someone to bite (if years later), so this is my guess. If the coil were going in just one direction, the entirety of the magnetic field would be pointing in one direction. The fact that the coil loops around and goes the other way means that the magnetic fields produced by the windings cancel each other out pretty effectively, though not perfectly -- the are regions where one winding or the other is producing a stronger magnetic field. This, in conjunction with the alternating current that is no doubt running through the copper coil, means that the aluminum is getting constantly jerked around with ever-changing magnetic fields that stress its crystal structure.
YOUR crystal structure is about to get constantly jerked around, poindexter!

I guess under no circumstances should one insert their penis into those coils.
You would be very disappointed. Nothing would happen.
Just don't do it while the molten aluminum is in there.
Your penis would probably be fine as it's not electrically conductive.

OTOH A chrome strap-on would make you light up like a Christmas tree.

Anyone remember the POERed page where the guy implanted lots of ball bearings, lights, and other objects into his penis? It weighed several pounds and was horribly infected. Anyone? I thought I had wiped it from my memory, but this thread brought it right back.
