Description	English: Meissner effect. Original caption : "In the late 1980s, Pacific Northwest National Laboratory researchers conducted research into superconductors. The ceramic superconductors are made from a material that has only very low alternating-current resistance and thus dissipates less power. Magnetic forces between the magnet and ceramic superconductor provide a magnetic cushion that keeps the magnet suspended above the superconductor. Liquid nitrogen cools the superconductor to minus 279 degrees Fahrenheit, producing the magnetic cushion." Français : Effet Meissner avec superconducteur en céramique refroidi par nitrogène liquide.
