Very interesting test!  Copper conductivity goes way down when in LN2.
Better look up the dielectric breakdown threshold.  Or pull the coil out
of the LN2 bath and run it in air while in a zero-humidity tent, otherwise
you get condensation and frost.  And you'll boil off lots of it while your
coil is cooling, so buy many liters.

I recall that Tesla mentioned "liquid air" cooling during Wardenclyffe
years.

Also, for liquid nitrogen you'd need a HTSC ceramic copper-oxide coil.
Common superconductive metals are lead and mercury, but you need liquid
helium dewar inside a liquid nitrogen jacket for those.
