Superconductivity and carbon nanotubes, are Type I, while almost all impure and compound superconductors are Type II. Conversely, a spinning superconductor generates a magnetic field, precisely aligned with the spin axis. The effect, the London moment, was put to good use in Gravity Probe B. This experiment measured the magnetic fields of four superconducting gyroscopes to determine their spin axes. This was critical to the experiment since it is one of the few ways to accurately determine the spin axis of an otherwise featureless sphere. Superconductivity was discovered on April 8, 1911 by Heike Kamerlingh Onnes, who was studying the resistance
FFC Heike Rheine FFC Heike Rheine FFC Heike Rheine was a German women's football club based in Rheine, North Rhine-Westphalia. Heike Rheine was the first independent women's football club in Germany. The club has its origins at the VfB Rheine. They had played on a local level until 1986 when Alfred Werner took over the head of the women's section. Two consecutive promotions in 1988 and 1989 took the club to the Regionalliga (West), then Germany's top football league for women. A second place in their first season 1989–90 qualified Heike Rheine for the newly founded Bundesliga. In 1992 and 1993 they finished
