Explanation To solve this problem, we need to understand the magnetic properties and their corresponding magnetic susceptibilities ( Ļ ) . (\chi). \newline ( Ļ ) . Let's analyze each type: ā¢ \newline ā¢ ā¢ Diamagnetic materials: ā \\
- ā These materials have a negative susceptibility, typically very small. ā \\
- ā The range for diamagnetic susceptibility is 0 > Ļ > ā 1. ā 0 > \chi > -1. \\
- 0 > Ļ > ā 1. ā

Therefore, A matches with II.
Ferromagnetic materials:
These materials have a very high positive susceptibility.
The susceptibility is much greater than 1, i.e.,
Ļ > > 1. ā \chi >> 1. \\
- Ļ >> 1. ā Therefore, B matches with III.
Paramagnetic materials:
These materials have a small positive susceptibility.
The range is
0 < Ļ āŖ Īµ 0 < \chi \ll \varepsilon 0 < Ļ āŖ Īµ (a small positive number).
Therefore, C matches with IV.
Non-magnetic materials:
These materials have zero susceptibility.
Thus,
Ļ = 0. ā \chi = 0. \\
- Ļ = 0. ā Therefore, D matches with I.
Based on the above analysis, the correct matching is:
A->II, B->III, C->IV, D->I.
This corresponds to Option 3.
