Differentiate between Type-1 & Type- II Superconductors.
|Sr. No.||Type I superconducters||Type II superconductors|
|1.||They exhibit complete Meissner effect.||They exhibit partial Meissner effect.|
|2.||There are perfect diamagnetics.||They are not perfect diamagnetics.|
|3.||These are known as soft superconductors.||They are known as hard superconductors.|
|4.||They have only one critical magnetic field.||They have two critical magnetic fields.|
|5.||These material undergo a sharp transition from the superconducting state to the normal state at the critical magnetic field.||
These materials undergo a gradual transition from the superconducting state to the normal state between the two critical magnetic fields.
|6.||The highest value of critical magnetic field is 0. 1 WB/m2||The upper critical magnetic filed can be of the order of 50 Wb/m2|
|7.||Application are very limited.||They are used to generate very high magnetic fields.|
|8.||Examples: Lead, Tin, Mercury, etc||Examples: Alloys like Nb-Sn, Nb-Ti, etc.|
