But it's not, is it? The keeper itself is not a magnet, just a non-magnetised lump of metal. [[Special:Contributions/86.26.33.25|86.26.33.25]] ([[User talk:86.26.33.25|talk]]) 14:46, 12 February 2024 (UTC)@

"Leak of into space"?!? That really isn't whats happening... —Preceding unsigned comment added by 193.157.234.158 (talk) 14:48, 25 April 2010 (UTC)[reply]

I removed that weird comment. Would need a cite for it (if it were really correct as written) or at least a clearer wording (to explain what really is happening). But it's idea is already covered earlier in the article, and I don't see evidence it's limited to horseshoe magnets. DMacks (talk) 17:19, 25 April 2010 (UTC)[reply]

Coercivity of AlNiCo magnets

[edit]

Article states "it is particularly useful for magnets which have a low magnetic coercivity, such as Alnico magnets.". However, the article for AlNiCo states that "Alnico alloys are ferromagnetic, with a high coercivity". Which is correct? 50.79.45.157 (talk) 21:32, 25 September 2014 (UTC)[reply]

Permanent magnet?

[edit]

A keeper for low-coercivity magnets is just a strong permanent magnet that keeps all the domains pointing the same way and realigns those that may have gone astray.

But it's not, is it? The keeper itself is not a magnet, just a non-magnetised lump of metal. 86.26.33.25 (talk) 14:46, 12 February 2024 (UTC)@[reply]
