| German | German Demonstration und Erläuterung zur Supraleitung Typ I.: spontanes Absinken des elektrischen Widerstandes eines Zinndrahtes beim Abkühlen (Unterschreiten der Übergangstemperatur); persistierender Strom in einem Zinnring. Magnetische Effekte, erniedrigte Übergangstemperatur durch starkes Magnetfeld, Meißner-Ochsenfeld-Effekt. Quantenmechanische Effekte (Energie-Defekt). |
| English | English Looks at measurements indicating the disappearance of electrical resistance in the transition to the superconducting state. Considers the temperature of transition, the exclusion of magnetic flux (Meissner effect), shielding currents, the "floating magnet," and persistent currents. Includes a discussion of the tunnel effect in connection with experiments involving an electron tunneling junction. |
