Match List-I with List-II

List  - I (Material)	List - II ((Susceptibility (x))
A. Diamagnetic	I. χ = 0
B. Ferromagnetic	II. 0 > χ ≥ − 1
C. Paramagnetic	III. χ >> 1
D. Non-Magnetic	IV. 0 < χ < εe (a small positive number)

Choose the correct answer from the options given below:

We are asked to match each type of material in List‑I with the appropriate range of magnetic susceptibility given in List‑II.

First, recall the typical susceptibility behavior of the four categories:

• Diamagnetic substances have a small negative susceptibility; they are weakly repelled by a magnetic field. In the table this is represented by the interval “0 > χ ≥ −1”.

• Ferromagnetic substances show a very large positive susceptibility, often many orders of magnitude larger than 1. This corresponds to “χ ≫ 1”.

• Paramagnetic substances have a small positive susceptibility, but it is still much less than 1. The table describes this as “0 < χ < εₑ” where εₑ is a small positive number.

• Non‑magnetic (or essentially magnetically neutral) materials have essentially no response to a magnetic field, i.e., their susceptibility is zero: “χ = 0”.

Now we match each material with the matching description from List‑II:

1. A. Diamagnetic → matches condition II (0 > χ ≥ −1).
Hence A–II.

2. B. Ferromagnetic → matches condition III (χ ≫ 1).
Hence B–III.

3. C. Paramagnetic → matches condition IV (0 < χ < εₑ).
Hence C–IV.

4. D. Non‑Magnetic → matches condition I (χ = 0).
Hence D–I.

Putting the four matches together gives the final answer:

A–II, B–III, C–IV, D–I
