Video of the week: Upside-down ‘levitation’ of superconducting puck

By Eileen De Guire / October 31, 2011

The phenomenon of superconductivity was discovered in 1911. Fifty years of physics research followed, and in 1962 Westinghouse introduced the first commercial superconducting wire, a niobium-titanium alloy wire. Its critical temperature is in the 10 K range, and, to reach those temperatures, liquid helium is used as a coolant. The next big breakthrough occurred in…
