Superconductivity

Context

On April 8, 1911, Dutch physicist Heike Kamerlingh Onnes discovered the phenomena of superconductivity.

What is superconductivity?

  • Superconductivity is the ability of certain materials to conduct a direct electric current(DC) with practically zero resistance.
  • This capacity produces interesting and potentially useful effects. For a material to behave as a superconductor, low temperatures are required.
  • Application: They are used in creating powerful electromagnets in MRI scanners, particle accelerators, generators, transportation, computing, electric motors, medical, power transmission, etc.

Fact Box:

  • Superconductivity was discovered in 1911 by Heike Kamerlingh-Onnes. For this discovery, the liquefaction of helium, and other achievements, he won the 1913 Nobel Prize in Physics.
  • Five Nobel Prizes in Physics have been awarded for research in superconductivity (1913, 1972, 1973, 1987, and 2003).
