kiaer.ts Posted January 29, 2009 Share Posted January 29, 2009 You can see a really cool demo of superconductor levitation here. Follow the link and then scroll down to chapter 8, superconductivity. The whole show - the whole site - is wonderful. Link to comment Share on other sites More sharing options...

Follow the link and then scroll down to chapter 8, superconductivity. The whole show - the whole site - is wonderful.Nice site. Thank you for the pointer. However, levitrons do not depend on superconductivity. The depend on gyroscope precession and a balance of attracting and repelling magnetic forces to avoid being bitten by Ernshaw's Theorem. The Ernshaw Theorem says that a static array of magnetic forces or electrical forces is impossible (Google or Wiki for the details). You can buy a magnetic levitating top and play with it without investing in cold stuff.Ba'al Chatzaf Edited January 29, 2009 by BaalChatzaf Link to comment Share on other sites More sharing options...
