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,
Heike Langguth Heike Langguth Heike Langguth (born October 22, 1979) is a German two times vice-champion in Muay Thai. Heike Langguth began her athletic career as a boxer and trained a little later in Weimar kickboxing. In 2004, she started at the 1 SSV Hall Field 92 eV with Muay Thai. That same year she became German Vice-champion and could repeat their success 2005th In 2006, she founded the association 'Bareknuckle eV', which operates a training center for Muay Thai, Kickboxing and traditional Boxing Eckartsberga malls village. Langguth works as a trainer and is effective for the training center Bareknuckle Gym Germany;
