You know, you would think that if someone discovered a mysterious stone containing almost no iron that exhibited magnetic properties in a novel way, with only one magnetic pole, there would be more analysis of it and more written about it by the scientific and engineering communities

One of my favourite metals is Bismuth. I found an excuse to write about it last year: https://coinofnote.com/1oz-bismuth-ingot/

If you enjoyed that, and are a little science-ey, you may like this video by The Action Lab on the strange #magnetism of #Bismuth: https://www.youtube.com/watch?v=g-77EcyI9iY He does a lot of really interesting #science videos if you like that kind of content :)

Yes. The three forms are:
Attraction
Repulsion, and
Whatever this thing is we have going on between us.

Fascinating.

"In a string of results over the past few years, researchers have shown that an idealized substance resembling two intermingled magnets can — in theory — maintain an orderly pattern no matter how hot it gets. The discovery might influence cosmology or affect the quest to bring quantum phenomena to room temperature."

Called it! I knew it was length contraction. Feeling not so stupid today!

I always wondered why a moving charge would induce a magnetic charge. It seems that the phenomena can be explained by just Coulomb's law and special relativity instead.
