Why Are Alloys More Effective for Magnetic Shielding Than Single Elements?

[miloko]

Hi all,

I was looking into magnetic shielding materials. I have the impression that nickle, copper, steel standalone are good shileding materials. However, some people claim that an alloy of these elements (eg. netics) are better shielding materials. Is this simply an empirical measurement or is there a scientific reason behind it?

Thanks,
Michael

I don't have an answer to your question, but I did find this interesting link.
