List - I		List - II
A.	Diamagnetic Material	I.	Small positive susceptibility
B.	Paramagnetic Material	II.	Negative susceptibility
C.	Ferromagnetic Material	III.	Large positive susceptibility
D.	Antiferromagnetic Material	IV.	Opposite equal magnetic moments

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

Hint:

Diamagnetic materials have negative susceptibility; ferromagnetic materials have large positive susceptibility.

Answer 1

The Correct Option is A

Concept:
Magnetic materials are classified according to magnetic susceptibility and alignment of magnetic moments.

Step 1: Diamagnetic material.
Diamagnetic materials have negative susceptibility and are weakly repelled by magnetic field. \[ A\rightarrow II \]

Step 2: Paramagnetic material.
Paramagnetic materials have small positive susceptibility. \[ B\rightarrow I \]

Step 3: Ferromagnetic material.
Ferromagnetic materials have large positive susceptibility and strong magnetization. \[ C\rightarrow III \]

Step 4: Antiferromagnetic material.
Antiferromagnetic materials have opposite equal magnetic moments, so net magnetization cancels. \[ D\rightarrow IV \] Therefore: \[ A-II,\ B-I,\ C-III,\ D-IV \] \[ \therefore \text{Correct Answer is (A)} \]
