Question

Match List I with List II.

List I (Material)		List II (Subsceptibility(χ))
A.	Diamagnetic	I.	χ = 0
B.	Ferromagnetic	II.	0 > χ ≥ –1
C.	Paramagnetic	III.	χ >> 1
D.	Non-magnetic	IV.	0 < χ < ε (a small positive number)

Choose the correct answer from the options given below:

• A. A-II, B-III, C-IV, D-I
• B. A-II, B-I, C-III, D-IV
• C. A-III, B-II, C-I, D-IV
• D. A-IV, B-III, C-II, D-I

Answer 1

The Correct Option is A

To correctly match List I with List II, we must examine the typical magnetic susceptibility (χ) values for each material type in List I.

1. Diamagnetic materials exhibit a negative susceptibility, generally close to zero, within the range 0 > χ ≥ –1.

2. Ferromagnetic materials are characterized by very high susceptibility values, χ >> 1, owing to their strong magnetic ordering.

3. Paramagnetic materials display small, positive susceptibility values; thus, their susceptibility range is 0 < χ < ε, where ε represents a small positive value.

4. Non-magnetic materials possess negligible susceptibility, indicating a value of χ = 0.

These characteristics lead to the following correct matches:

A-II: Diamagnetic materials correspond to a susceptibility of 0 > χ ≥ –1.

B-III: Ferromagnetic materials correspond to a susceptibility of χ >> 1.

C-IV: Paramagnetic materials correspond to a susceptibility within the range of 0 < χ < ε.

D-I: Non-magnetic materials correspond to a susceptibility of χ = 0.

The definitive correct option is: A-II, B-III, C-IV, D-I
