Verpies:
What I think we are seeing in the video that you re posted, is speaker wire. Which is not what I'm using, at all.
https://www.homedepot.com/p/Commercial-Electric-50-ft-14-Gauge-Stranded-Speaker-Wire-Y283530/203726262 As this particular speaker wire has two different conductors, copper and aluminum, perhaps a reaction of some sort may have happened there.
Nor do we know how long the effect last for. Nor, if it's even that type of speaker wire, as there is also just CU speaker wire, as well. Which looks very similar to the dual metals speaker wire. So, we don't know which speaker wire is being used, in the video. Or how old, cheaply made, or burnt out, it may be. I don't understand Russian, either, maybe Vasik can chime in on some details.
As mentioned, I doubt that it is a similar device to mine, nor do I think that wire has anything to do with MO, of my device. As it may be a consequence of some sort of short circuit, and such, so it's hard to tell. And is not something that I've ever observed. So, I pass on judgement, as to the cause of the anomaly.
I use regular house construction copper wire. Not the dual metals speaker wire, nor the same metals copper speaker wire.
So, I can't compare apples to mangos. I just post this, as you are talking about copper and aluminum becoming magnetic, NOT just copper wire, like I use. I hope that this helps.

PS. What I have noticed while living in a very hot 90 percent humidity climate, is that everything here oxidizes very very fast. Including speaker wire, sealed in PVC. You can see it right through the clear insulation. And that coating on the wires may in time cause some type of anomaly, such as on that piece of magnetic wire. Especially when exposed to repeated HV pulses, along with lower voltage pulses from the induction circuits, as on my device. That coating may change things. Until the wire dissolves, or turns to dust.
