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-
• 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

Concepts:

Magnetic properties, Magnetic susceptibility

Explanation:

To match the materials with their corresponding magnetic susceptibilities, we need to understand the properties of each type of material:

• Diamagnetic materials have a small negative susceptibility (χ).
• Ferromagnetic materials have a very high positive susceptibility (χ≫1).
• Paramagnetic materials have a small positive susceptibility (0<χ<ε).
• Non-magnetic materials have zero susceptibility (χ=0).

Step by Step Solution:

Step 1:

Identify the susceptibility of diamagnetic materials: 0 > χ ≥ −1 (small negative value).

Step 2:

Identify the susceptibility of ferromagnetic materials: χ ≫ 1 (very high positive value).

Step 3:

Identify the susceptibility of paramagnetic materials: 0 < χ < ε (small positive value).

Step 4:

Identify the susceptibility of non-magnetic materials: χ = 0 (zero value).

Final Answer:

The correct matching is: A-II, B-III, C-IV, D-I. Therefore, the correct option is (3).
