Physicists have shown that an idealized form of magnetism is heatproof

The main result is not about magnetism, it is that it is possible within quantum field theory to have phenomena that are stable whatever the temperature is. That is really interesting.

Interesting. It would be huge if this can help room temperature superconductivity. It seems like nobody knows what to do with it yet though.

Isn't this why magnetism is used to contain plasma in stellerators?

Heatproof might have a limit. Every material has a failure point, some temperature when all the particles decide to part ways. Those arrows mean little once elections start moving around as individuals.
