it contains no rare-earth materials, which are both expensive and difficult to acquire.

Not at all true... rare-earth materials are not all that rare and the only expense comes from the fact that most of them (95%ish) come from just a few mines in China.  Other countries in the world have rare-earth resources; they just aren't utilized because Chinese prices were relatively cheap compared to the expense of mining for their own.

The All-Powerful Atheismo: it contains no rare-earth materials, which are both expensive and difficult to acquire.

In a first-world context, they are sort of expensive and difficult to acquire. They tend to be found in radioactive and otherwise hazardous areas, so the employment risk compensation aspects would drive the prices up a bunch.

So we let the Chinese do it.

Is vibranium a rare-earth material?

This text is now purple: In a first-world context, they are sort of expensive and difficult to acquire. They tend to be found in radioactive and otherwise hazardous areas, so the employment risk compensation aspects would drive the prices up a bunch.

Well really the major impediment is that we would have to do some serious underground mining (like gigantic open-pit mines) and that would require lots of up-front costs, environmental issues, etc.  They're still relatively inexpensive and not rare.

King Something: Miraculous.


This. That's just... amazing. Just farking amazing.

So ICP was actually asking a legitimate scientific question.

Duke's new magnets suck...

Very good headline, and rather interesting article, subby! Good work! :-D

Oh god they used models. Are we going to see a rise in magnet denialists?

Fortunately, there is a way to find out if the model is going in the right direction. Some kind of tool which confirms whether a material is actually magnetic.

I'm sure they'll iron out those details...

Okay, so these are new *magnetic materials*, not new 'types of magnets'. (Ferromagnetic, paramagnetic, diamagnetic, anti-ferromagnetic, and ferrimagnetic being the main three, if I remember correctly.)

I admit I was inexplicably drawn into the article by the attractive headline.  But I was then repulsed by the web site.

/Anyway, magnets are magic, I don't care what you say.
