Consider the following statements with respect to superconductivity:1....
- Superconductivity refers to complete disappearance of electrical resistance in various solids when they are cooled below a characteristic temperature. This temperature, called the transition temperature, varies for different materials but generally is below 20 K (-253 °C). Hence statement 1 is not correct.
- The superconducting material shows some extraordinary properties which make them very important for modern technology.
(i) In Superconducting state, the superconducting material shows the zero electric resistance (infinite conductivity).
(ii) A Superconductor, when it is cooled below the critical temperature Tc), expel the magnetic field and doesn’t allow the magnetic field to penetrate inside it. This phenomenon in superconductors is called Meissner effect. - Superconductors are used in the following applications:
(i) Maglev (magnetic levitation) trains: These work because a superconductor repels a magnetic field so a magnet will float above a superconductor - this virtually eliminates the friction between the train and the track. Hence statement 2 is correct.
(ii) Superconductors are used in Large hadron collider or particle accelerator, to make extremely powerful electromagnets to accelerate charged particles very fast (to near the speed of light),
(iii) SQUIDs (Superconducting QUantum Interference Devices) are used to detect even the weakest magnetic field. They are used in mine detection equipment to help in the removal of land mines.
