Directions: The question consists of two statements, one labeled as ‘Statement (I)’ and the other labeled as ‘Statement (II)’. You are to examine these two statements carefully and select the answers to these items using the codes given below:
Statement (I): Indium (Z = 49) in the superconducting state will exhibit incomplete Meissner’s effect and Silsbee rule.
Statement (II): The critical current is directly proportional to the critical magnetic field.
  • a)
    Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I).
  • b)
    Both Statement (I) and Statement (II) are individually true, but Statement (II) is not the correct explanation of Statement (I).
  • c)
    Statement (I) is true, but Statement (II) is false.
  • d)
    Statement (I) is false, but Statement (II) is true.
Correct answer is option 'D'. Can you explain this answer?

Superconductors are of two types:
  • Type 1 superconductors: These are ideal or soft superconductors. They have a low value of the critical magnetic field and transition temperature. They exhibit complete Meissner's effect and Silsbee rule. Eg: Pb, Pd, Hg, Zn, Al, In, etc
  • Type 2 superconductors: These are non-ideal or hard superconductors. They have a high value of the critical magnetic field and transition temperature. They exhibit incomplete Meissner's effect and Silsbee rule. Eg: NbTi, NbZr, etc
The current density at which the superconductivity of material disappears is called Critical current density. Critical current is given by the formula: IC = HC where R is the radius of the wire of a superconducting material having central current I and Hc is the critical magnetic field. The critical current is directly proportional to the critical magnetic field.

Explanation:

Statement (I) Analysis:
- In the superconducting state, a material exhibits the Meissner effect, which is the expulsion of magnetic field from its interior.
- Indium (Z = 49) is a type I superconductor, which means it exhibits complete Meissner effect, expelling all magnetic field from its interior.
- Silsbee rule states that the critical current density in a superconductor is proportional to the critical magnetic field.
- Therefore, Indium in the superconducting state will exhibit complete Meissner effect and follow Silsbee rule.

Statement (II) Analysis:
- Critical current is the maximum current a superconductor can carry without resistance.
- Critical magnetic field is the maximum magnetic field a superconductor can sustain while remaining superconducting.
- The critical current is directly proportional to the critical magnetic field in superconductors.

Explanation:
- Statement (I) mentions that Indium in the superconducting state will exhibit incomplete Meissner's effect and Silsbee rule, which is incorrect for a type I superconductor like Indium.
- Statement (II) correctly states that the critical current is directly proportional to the critical magnetic field in superconductors.
- Therefore, Statement (I) is false, but Statement (II) is true, making option D the correct choice.
