Question

Arrange the following in increasing order of their magnetic susceptibility:
A. Diamagnetic material,
B. Paramagnetic material,
C. Ferromagnetic material.

• A. A, B, C
• B. B, C, A
• C. A, C, B
• D. B, A, C

Hint:

Increasing magnetic susceptibility order is diamagnetic \(<\) paramagnetic \(<\) ferromagnetic.

Answer 1

The Correct Option is A

Concept:
Magnetic susceptibility tells how strongly a material responds to an applied magnetic field.

Step 1: Diamagnetic material.
Diamagnetic materials have small negative susceptibility. \[ \chi<0 \] So, they come first in increasing order. \[ \text{First}=A \]

Step 2: Paramagnetic material.
Paramagnetic materials have small positive susceptibility. \[ \chi>0 \] So, they come after diamagnetic materials. \[ \text{Second}=B \]

Step 3: Ferromagnetic material.
Ferromagnetic materials have very large positive susceptibility. \[ \text{Highest}=C \]

Step 4: Final order. \[ A,B,C \] \[ \therefore \text{Correct Answer is (A)} \]
