Superconductors and the 'Meissner effect'
Mark Miodownik explores the amazing properties of superconductors. He shows how superconductivity can make a magnet levitate above a piece of ceramic (yttrium barium copper oxide). This phenomenon is known as the 'Meissner effect'. Mark also discuss the incredible potential superconductors could have in our lives in the future.
