    • Thumbnail: A magnet levitating above a high-temperature superconductor, cooled with liquid nitrogen. Persistent electric current flows on the surface of the superconductor, acting to exclude the magnetic field of the magnet (Faraday's law of induction). This current effectively forms an electromagnet that repels the magnet. (CC BY-SA 2.0 Generic; Mai-Linh Doan via Wikipedia)
