Magnetic Fields record

World record: The strongest magnetic fields created
On June 22, 2011, the Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 teslas. To reach this record, Sergei Zherlitsyn and his colleagues at the High Magnetic Field Laboratory Dresden (HLD) developed a coil weighing about 200 kilograms in which electric current create the giant magnetic field – for a period of a few milliseconds. The coil survived the experiment unscathed.

New Green Transportation


New electric diwheel hints at future of city transportation
New electric diwheel hints at future of city transportation (PhysOrg.com) -- In a bit of technical wizardry, students from the University of Adelaide, Australia, have devised and built an electric diwheel, that with modification, could possibly solve inner city transportation problems. The team, comprised of 14 mechanical engineering students, has taken the idea of a diwheel and quite literally, turned it on its head, and in the process have created a vehicle that could be used to safely transport people around; all with a minimum amount of energy.



Applying Einstein's General Theory of Relativity to Superconducting Circuits

ScienceDaily (June 11, 2011) — In recent years, UC Santa Barbara scientists showed that they could reproduce a basic superconductor using Einstein's general theory of relativity. Now, using the same theory, they have demonstrated that the Josephson junction could be reproduced. The results are explained in a recent issue of the journal Physical Review Letters.
