SpletThis is the Meissner effect. In the right panel, a metal tube is placed on a magnet. The magnet's diameter is slightly smaller than the inner diameter of the tube, so the magnet can slide freely. The metal tube is rapidly lifted up by hand. The magnet is seen to move up together with the metal tube. Hence the magnet was lifted by the normal metal.
