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.
