If you can get an MRI magnet that would definitely do the trick. Just don't move it on an axis within 50 feet of any discs or tapes. By the way, opening the fridge door would count as moving it on an axis.

what material are the cow magnets made of?

Alnico I think. We made those only once There pretty damned big actually, I was suprised.

No, not as far as I know. I think they're quite a bit lower on the rare-earth scale, if even at all.

They're stronger than your general ceramic magnet though, for sure.

No. They get alot of the oomph from their size.
