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,

In 2009, Heike Hennig was invited to teach at the University of British Columbia in Vancouver and Kelowna as well as at Simon Fraser University in Burnaby, Canada as a "Guest Speaker" via film, workshop and lectures. Since 2010, Heike Hennig has taught at the Zurich University of the Arts (ZHdK).
