Magnets have an annoying tendency to stop working when they are heated.

And it's ridiculous that I'm saying that on the context of testing a superconductor. But well, here we are.

You could always use an electromagnet.

A superconducting one?

No, we're talking about verifying superconductivity using a traditional magnet at an elevated temperature.

Yes, but that's quite a bit of extra complication on an experiment of some material that was announced into the world last Friday.

I do expect people to fully characterize it eventually.

Indeed, that statement would have been really funny just a few weeks ago. Now you're going to have to wonder whether the magnet or the superconductor will fail first.

Neo magnet fabrication is fascinating by the way, the somewhat magnetized blanks are not all that impressive from a magnetic field strength point of view, but then you zap them with a strong enough field and they then suddenly are the best thing since sliced bread.

This technique was first developed for 'regular' ceramic magnets.

An uncoated magnet will oxidize very fast, so you always have to ensure that the coating on any magnets you use is perfect or the magnet will surely fail.
