(a) Explain the Meissner effect of flux expulsion in along superconducting wire arranged with its axis parallel to amagnetic field using the differential form of Faraday law ofelectromagnetie induetion. (b) Illustrate that the supereonductornot only excludes external magnetic field, it expels fields thathas been established inside the superconductor using the graphicalway such as B vs. H plot.
