Match List-I with List-II.
List-I (Material):
A. Diamagnetic
B. Ferromagnetic
C. Paramagnetic
D. Non-magnetic
List-II (Susceptibility ($\chi$)):
I. $\chi = 0$
II. $0 > \chi \geq -1$
III. $\chi >> 1$
IV. $0 < \chi < \varepsilon$ (a small positive number)
Choose the correct answer from the options given below:
Answer: (C) A-II, B-III, C-IV, D-I
Concept. Materials are classified by the sign and size of their susceptibility $\chi$.
Step 1. Match each class.
- Diamagnetic: small negative $\chi$, with $-1 \leq \chi < 0$ → II.
- Ferromagnetic: very large positive $\chi$, $\chi >> 1$ → III.
- Paramagnetic: small positive $\chi$ → IV.
- Non-magnetic: $\chi = 0$ → I.
Answer. A-II, B-III, C-IV, D-I (Option C).
