Thanks for the link! I remember having seen it some years ago but couldn't find it again. Now I'll bookmark it ;)

Interesting for sure. I've seen this around for a long time now and keep forgetting to make a link or just copy the thing.

Nickel
Usually used in an alloy with copper (see cupro-nickel) or iron (see stainless steel), although the pure metal has been (and is) used a great deal, notably for the coins of Switzerland and Canada. It was first used in this form by Switzerland in 1881. The pure metal is magnetic, and is noticeably yellower than some of the silvery metals such as chromium and aluminium. just carl, do you disagree with this statement from the website? I'm not asking to prod or poke you, because I do know you are from a scientific background. I know nothing about the subject, and find it interesting that there could be disagreement on the subject of whether an element is (in its natural state) magnetic or not. |

Yes, I'm intersted too. I thought nickel was the reason (most) stainless steels aren't magnetic?

I want to say it is because the iron and the nickel will "cancel each other out" but I am sure there is a more accurate way to describe it. Time for some research.  Edit: I found several mentions that the combination affects the way electrons are able to align, therefore affecting the effect of magnetic fields. |

That got my curiosity, like a cat, if nickel's magnetic or not. here's the pics, test made now during breakfast (I just couldn't wait  ) the coin is the Philippine 10Peso 100% Pure Nickel 1988 36mm commemorative coin. Magnet is a strong Torroidal type used on Audio speakers (this one pulled from a base woofer). Yes! Nickel's highly magnetic     |

Nic, thanks for showing that, pretty cool. Quote:
Yes! Nickel's highly magnetic The question isn't whether nickel *can* be magnetic. It is whether nickel is naturally magnetic. This topic started in another thread, but I don't know where it is... |

Pure nickel is magnetic. Alloyed nickel however is not.

Alloyed nickel however is not. As just carl was saying in the other thread, one of the strongest magnets is a nickel alloy: AlNiCo |
