Superconducting magnet issues "shaken" out of them, until they are eventually able to operate reliably at their full planned current without experiencing quenches. Although the idea of making electromagnets with superconducting wire was proposed by Heike Kamerlingh Onnes shortly after he discovered superconductivity in 1911, a practical superconducting electromagnet had to await the discovery of superconducting materials that could support large critical supercurrent densities in high magnetic fields. The first successful superconducting magnet was built by G.B. Yntema in 1955 using niobium wire and achieved a field of 0.7 T at 4.2 K. Then, in 1961, J.E. Kunzler, E. Buehler, F.S.L. Hsu,
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
