I have had opportunity to play with the inards of magnecore wire. Its a
spiral wound resistance wire, with a good quality silicone jacket.
Size definatly doesnt matter as far as energy is concerned, but the
jacket thickness has a great deal to due with the voltage that the wires
will take before the jacket insulation breaks down, so if you are running
a 40 or 60 kv coil, then its not a bad idea to use the larger jacket
wires to prevent arcing.
The issue with he spring and its small size in relation to the wires is
also a non-issue becuase the high tension side of the coil lacks substancial
current, and small conductors "spring wire" will easily pass the ignition
current without heating the conductor.
I think in the best of ignition systems "low inductance coil CD", the wire
current is less than 1 ampere peak when the combustion chamber ionizes and
the plug is essentially shorted to ground. Otherwise the ingition current
is perhaps 10 ma average across 1 millasecond producing about 100 mj
of spark energy.
