Question

Critical temperature of a superconductor when no magnetic field is present is tc. find the temperature at which the critical field becomes half of its value at 0k

Answer 1

Answer:

Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic flux fields are expelled from the material. Any material exhibiting these properties is a superconductor.

Answer 2

The critical temperature of the superconductor when no magnetic field is present is Tc and the temperature at which the critical field becomes part of its value in 0k is:

• The superconductor is generally considered to have a high temperature when it reaches a superconducting state where it is cooled using liquid nitrogen i.e., at Tc> 77 K) only - or at low temperatures when aggressive cooling techniques are needed to reach critical temperatures.
• A certain number of magnetic fields in addition to which superconductors return to a state of operation is called an important magnetic field.
• The number of sensitive magnetic field measures against temperature.
• As the temperature rises, the value of the vital magnetic field decreases.
• This delicate magnetic field is placed in a 0K table and descends from that magnitude with increasing temperature, reaching the egg at the critical temperature of the highest performance.
• The magnetic field that is important at any temperature below the critical temperature is given to the relationship.
