ahmeeeeeeeeeed Posted June 16, 2011 Share Posted June 16, 2011 Hello What does the " diamagnetics Repulsion" with a magnet mean ?? does copper for example do that ?? 2- When we are talking about super conductors and maisner phenomenon What causes it ? Is there a current initially in the superconductor ? Or is the current induced by the magnet ?? Link to comment Share on other sites More sharing options...
swansont Posted June 16, 2011 Share Posted June 16, 2011 Diamagnets repel because the magnetic dipoles induced in the diamagnet line up anti-aligned with the external field (N-N or S-S) http://en.wikipedia.org/wiki/Meissner_effect Link to comment Share on other sites More sharing options...
