This seems to be closely related to the "Z-pinch" effect as practiced
There are not really any "new" laws of physics there, but rather the
old ones applied carefully to a specific situation. I imagine they
known the associated effects very well.
The wire fragments I have were originally in a coil which adds too
much uncertainty. I straight wire would tell far more as would super
high speed photography... With motion pictures, you could tell if
there were physical resonances and such tearing the wire.
At 03:57 AM 4/25/2006, you wrote:
I have the pleasure of exploding a few wires and also have a wire
collection from my 16kJ cap bank. I did a test fire of a can crush
with fine wire (.024inch) in a plastic tube to see if the resulting
plasma channel was sufficient to give a crushing
current. Experimental setup is here.
The net result at 4 kJ was slight denting of the can (perhaps
equivalent to 500J worth) with no remaining charge on the cap. So
the plasma held until the cap emptied but did not allow a high
enough peak current compared to the wire. I did not control for the
reduced physical strength of the plastic tubing compared to the wire
however. With the heavy wire, the can is torn in three pieces in that setup.
I don't really see why new physics is suggested by this. The
radially expanding wire with a uniform force will bring out
inhomogeneities in the wire and magnify them into physical rupture
points. (in a way somewhat analagous to the Big Bang giving
microwave background irregulatities, but that would really imply
some new physics...).
I got a batch of your shrunken quarters years ago and I requested
to get the "wire fragments too" ;-)))
"Normal" people get a kick out of the coins, but "I" got the wires
too since that is what is "really cool" :o))
........ There are inertial and explosive forces that tend to bend
the wire up too along with impacts to the containment walls... The
wire fails in weak areas that become dominate fracture areas. I
suspect plasmas became conductors as the system ripped apart too.........
