The Nobel for physics was announced,
http://www.nobel.se/physics/laureates/2003/press.html
and in the article it refers to superconductors which can 'displace magnetic flows'.

Can anyone explain a bit?

babs- At the bottom of the page they have a link to information for the public. Within that page they have a little more of an explanation as well as a diagram of the effect.

btw, they also have a more advanced discussion.

Do those help?

Sure does, Meth. Sorry about that. When I encountered a term which conveyed absolutely nothing to me, my brain went into fugue mode and insisted I go away and find out what the mystery term meant before continuing. I didn't hang around long enough to see that the answer was close at hand.

Thanks for the help.

No need to apologise. I might not have read further either, if I hadn't remembered from past Nobel prizes that they usually have these three pieces (a short press release, a more detailed piece, and a more technical piece), at least for the scientific awards.
