Meissner effect: Superconductivity and magnetic field do not like each other. The superconductor will expel all the magnetic field from inside... ..... Any spatial movement of the superconductor will cause the flux tubes(the magnetic field penetrates in discrete quantities called flux tubes) to move which the superconductor tries hard to prevent, thus remaining "trapped" in midair. bernard On Wed, Oct 19, 2011 at 3:22 PM, geoffrey gitagia <ggitagia@gmail.com>wrote:
