Superconductivity, how does it work? See this video made by Radomir Niewrzol of Argonne National Laboratory, and learn about this cool phenomenon. There is more information below about Superconductivity, with a link to another page to read more.
Physicist Kamerlingh Onnes cooled mercury to 4.2 degrees Kelvin, or -450 Fahrenheit, and discovered that it conducted an electric current perfectly—no electricity was lost as heat or friction. This phenomenon is called superconductivity. An electric current in a loop of a superconductor could, theoretically, last forever; in experiments they have been observed to last for years.
Superconductors have already given us MRIs, particle accelerators and better cell phone reception, but further improvements could revolutionize technology as we know it. The trouble is, they still hold some of the greatest mysteries in physics. Read more!
