Superconductivity: properties and challenges
IN SHORT Definition: State of a material at very low temperature capable of conducting an electric current without resistance. Meissner effect: Expulsion of magnetic fields when transitioning to the superconducting state. Applications: Lossless electricity transmission, magnetic levitation, magnetic resonance imaging. Fascinating properties: Indefinite circulation of a current in a superconducting ring. Challenges: Understanding the mechanisms … Read more
