Critically, during the compression stroke the noble gasses are not
in a conductive state. The helium atoms are likely very thoroughly
mixed, although I'm open to arguments to the contrary.
Moreover, when I talked to Bob, he said that the current through the
coils was very low. I don't recall what the current was, but to
achieve significant magnetic confinement you need high currents.
I thought the purpose of the coils was to generate the high voltages
for the spark.
