Hmm, I see the spool of fishing wire on top of the wooden blocks with some vacuum tube poking their heads out of the driver I would assume. My only guess left is that you are retracting the fishing line whilst it is sparking? But thats awfully close to my other guess...
Ill have a long look and try to figure out more.
You were right before essentially. I feed out the magnet wire from the spool and it has a 2 inch gap in it joined by nylon line.

Can you see the potential for one with dimensions 20 times as big?

Hmm, a spinning dish with steam, or cold CO2 or N2 fuming out an orifice?

Yes that is a NIB (Neodymium-iron-boron) magnet which is probably about 5mm diam. No it wasn't LN2 (and it wouldn't float anyway).
Getting closer though.
