Steve Koch 23:32, 28 April 2010 (EDT): cool! looked like your data today was going to show a significant difference between yoke / non-yoke. at some point we'll have to figure out why that is. I guess even these super-strong permanent magnets relax a bit when external field is reduced. That's what I was originally thinking but then recently had been convincing myself it wasn't significant. Obviously I need to think more. :)
