Superconductivity Type I superconductors – expel all magnetic fields below a critical temperature, T c (Meisner effect).
{"Image DocumentName": "SuperconductivityConduct electricity without resistance below a certain temperature.", "Image ImageDescription": "Once set in motion, electrical current will flow forever in a closed loop. Mercury(Hg) behave like superconductor below 4 K. Type I superconductors \u2013 expel all magnetic fields below a critical temperature, Tc (Meisner effect). Type II superconductors \u2013 below a critical temperature exclude all magnetic fields completely. Between this temperature and a second critical temperature, they allow partial penetration by the magnetic field.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
