Choose the correct answer from the options given below:
| List-I | List-II |
|---|---|
| (A) Diamagnetic material | (I) |
| (B) Paramagnetic material | (II) |
| (C) Ferromagnetic material () | (III) is small, negative and independent of |
| (D) Superconductor | (IV) |
Choose the correct answer from the options given below:
Options
- A(A)-(II), (B)-(IV), (C)-(I), (D)-(III)
- B(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
- C(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
- D(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Correct answer
D. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Step-by-step solution
Diamagnetic materials have a small, negative susceptibility that is practically independent of temperature. Thus, (A) matches with (III).
Paramagnetic materials obey Curie's law, where susceptibility is inversely proportional to absolute temperature (). Thus, (B) matches with (IV).
Ferromagnetic materials above their Curie temperature () become paramagnetic and obey the Curie-Weiss law (). Thus, (C) matches with (I).
Superconductors exhibit the Meissner effect, acting as perfect diamagnets with a susceptibility . Thus, (D) matches with (II).
Answer: (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Paramagnetic materials obey Curie's law, where susceptibility is inversely proportional to absolute temperature (). Thus, (B) matches with (IV).
