Superconductor
Description
A substance that reaches superconductivity, a state in which magnetic fields cannot penetrate, and there is no electrical resistance, is referred to as a superconductor. In 1911, Heike Kamerlingh Onnes of Leiden University, a Dutch physicist, observed a relation between the temperature and the resistance of the element mercury. The mercury sampl...

Transcript
A superconductor is a material that offers zero resistance to the flow of electrons with an efficient transfer of electrical energy and no heat loss.
In 1911, Heike Kamerlingh Onnes observed that resistance goes to zero when mercury is cooled below 4.2 Kelvin. This is known as the critical temperature for mercury, and the phenomenon is kn...
