Main Question or Discussion Point

Hi all,

In one of the books I'm reading, it says that shields are only used in the presence of alternating fields. However, in some websites, I see people using magnetic shields for permanent magnets which has a magnetostatic field. I ran some simulations, and the filed of a permanent magnet seems to be shielded by a layer of nickel. So, who's telling the truth?

Thanks,
Michael

This person is wrong (emphasis added by me to point out error).

Static shields (like Mumetal) are commonly used in many applications. See the similar thread under the Materials Engineering subforum.
