Q. Math List-I with List-II. [table] List-I (Material) | List-II (Susceptibility ($x$)) ; (A) Diamagnetic | (I) $x=0$ ; (B) Ferromagnetic | (II) $0>x\geq-1$ ; (C) Paramagnetic | (III) $x>>1$ ; (D) Non-magnetic | (IV) $0<x<\varepsilon$ (a small positive number) [/table] Choose the correct answer from the options given below:
A) A-III, B-II, C-I, D-IV
B) A-IV, B-III, C-II, D-I
C) A-II, B-III, C-IV, D-I
D) C-II, B-I, C-III, D-IV
Explanation
[Solution by Claude - not from source] Diamagnetic: small negative $\chi$ ($0>\chi\ge-1$); ferromagnetic: $\chi\gg1$; paramagnetic: small positive; non-magnetic: $\chi=0$. So A-II, B-III, C-IV, D-I. Answer (3).
