watch to find out ;)

this is gooing up late because this video not only took a very long time to film but took 43 minutes to render and after that was done the internet was down.

If the powersupply still works, can you re-wire it outside the vaccuum chamber? I don't know if anything else in the electronics of the microwave will short in the vaccuum, but it could allow you to run the microwave with "external" power.

But why would arc go more easily in near vacuum, when there are less particles for electrons to jump across?

Eddy current loss, hysteresis loss, and I^2R loss are all types of energy loss in a normal transformer. This energy is lost as heat and must me cooled by natural convection. In large industrial transformers this is usually cooled by oil, but in small ones like this microwave transformer a simple fan will work. However if there are no air molecules to move and carry the heat, the coils will overheat, and the anodized coating will melt off letting the windings come in contact and shorting out/ creating arcs. (Smells like rubber --&gt; smells like burned coil juice) Also the hot smoke is then moved by the fan and scorches it. Thank for the video cody👍

you'd imagine air being LESS conductive with less air molecules being able to conduct electricity, on the other hand it might just make the air molecules that ARE in the vacuum chamber more likely to become plasma may be an interesting thing to experiment with (jacob's ladder in a vacuum chamber?)

Could you run the transformer to see if it works? If it does, could you run it inside the vacuum chamber and get some interesting results?

Possibly a vacuum arc? <a href="https://en.wikipedia.org/wiki/Vacuum_arc" rel="nofollow noopener" target="_blank">https://en.wikipedia.org/wiki/Vacuum_arc</a>

I don't suppose you would like a Tesla coil for your arc tests?

I don't think it is as much of a heat sink issue, with air being the sink, as much as I do think that the microwave emission setup might need air to direct the microwavesame to the intended destination. The eectromagnetic spectrum works, in the simplest form, better when obstacles are not in the way. The screen on the microwave door is big enough to let light pass through but not the larger microwaves. Maybe the distance between air particles has a dampening affect like the holes in the screen. Idk? You're smarter than me.

My first guess is that it is some effect similar to low pressure plasma in fluorescent lamps.
