Only Statement 2 is correct.
  • Superconductivity refers to a state in which a material offers zero, or near-zero, resistance to electric current. 
  • Superconducting materials show very interesting behaviour under magnetic field which allows the functioning of systems like the MRI scan machine and the superfast Maglev trains that float above the tracks. 
  • As of now, superconductivity can be achieved only at very low temperatures, more than 250 degree Celsius below zero, very close to absolute zero which is – 273 degree Celsius.

Consider the following statements regarding Superconductivity. Superco...
Statement 1: Superconductivity refers to a state in which a material offers high resistance to electric current.
This statement is incorrect. Superconductivity is actually the complete absence of electrical resistance in a material. When a material becomes superconductive, it allows electric current to flow through it without any loss of energy due to resistance.

Statement 2: MRI scan machine and the superfast Maglev trains work on the principle of Superconductivity.
This statement is correct. Both MRI (Magnetic Resonance Imaging) machines and Maglev (Magnetic Levitation) trains utilize the principle of superconductivity. In MRI machines, superconducting magnets are used to produce a strong magnetic field, which is essential for the functioning of the machine. Maglev trains use superconducting magnets to create a levitation effect, allowing the train to float above the track and eliminate friction, resulting in high speeds.

Statement 3: As of now, superconductivity can be achieved only at very high temperatures.
This statement is incorrect. The traditional understanding of superconductivity was that it can only be achieved at very low temperatures, close to absolute zero (-273.15 degrees Celsius). However, in recent years, high-temperature superconductors have been discovered, which can exhibit superconductivity at temperatures above the boiling point of liquid nitrogen (-196 degrees Celsius). While these temperatures are still considered low in everyday terms, they are much higher than the traditional superconducting temperatures.

In conclusion, only statement 2 is correct. Superconductivity refers to the complete absence of electrical resistance, and it has been utilized in various applications such as MRI machines and Maglev trains. While superconductivity was traditionally achieved at very low temperatures, high-temperature superconductors have been discovered, allowing for superconductivity at higher temperatures.
