Neodymium magnets are made from Iron

What part of NdFeB didn't you get?

I've never seen anyone claim that Neodymium magnets do *not* contain iron. The name is used to highlight the fact that it's the addition of Nd that works the magic and to distinguish it from magnets made from plain old steel and other alloys. Same thing with Alnico which also has a lot of iron in it..

Mostly when I've heard them referred to, they have been called neodynium-iron magnets.

Not quite. Neodymium's Curie temperature is rather low at 19K but it is antiferromagnetic. When combined with the right amount of iron and boron it forms an intermetallic ceramic compound with huge magnetisation.

Fe14Nd2B

being the most commonly favoured compound formulation.

Almost as strong Samarium Cobalt magnets slightly predate them. (with no iron)

"Rare earth" is something of a misnomer. They are quite common as trace elements in just about everything. So much so that they can be used as a signature for terroir in wines, meteorites and archeological finds.

I know the geologists get really excited by it since the Nd isotope ratio in a rock is a direct indicator of when it was last molten.

They would also be a lot lighter if you took the iron out.

Samarium?

The false advertising puts the amazing item first : pork and beans, Samarium Cobalt. Cobalt is ferromagnetic so it is listed last, after the amazing magnetic magic of Samarium, a nonferrous element.

What's the percentage of salt in salted peanuts?

Specificity, rather. Otherwise it'd be iron magnet vs. iron magnet. You don't have to be a marketeer to see the difficulty with that.

That's essentially what I said in different words in an earlier post. But it seems he chose to ignore it.

What's the percentage of salt in OP? I'm guessing 100%.
