(Material) | (Susceptibility ($$\chi))
Diamagnetic | (II) | 0 > _ � _ 1
Ferromagnetic | (III) | _ _ 1
Paramagnetic | (IV) | 0 < _ < _
Non-magnetic | (I) | _ = 0
To match the magnetic materials with their respective magnetic susceptibilities, we must understand the characteristics of each type of material regarding its magnetic behavior. Here are the implications of each type:
Diamagnetic Materials: These materials are repelled by magnetic fields. The susceptibility ( _ ) of diamagnetic materials is negative but very small, near zero. Therefore, _ > _ 1 and closer to zero, reflects this property.
Ferromagnetic Materials: They have a very high, positive susceptibility because these materials can be permanently magnetized. Their susceptibility ( _ ) is much greater than one ( _ >> 1 ).
Paramagnetic Materials: These materials are weakly attracted by a magnetic field, and their susceptibility is positive. However, the value of _ for paramagnetic materials is small but greater than zero ( 0 < _ < _ ), where _ represents a small positive value.
Non-magnetic Materials: For materials that are considered non-magnetic, the susceptibility ( _ ) is zero ( _ = 0 ), as they are neither attracted nor repelled by magnetic fields.
Let's match these descriptions with the given List II in your question:
Diamagnetic (A) matches with 0 > _ � _ 1 (II).
Ferromagnetic (B) corresponds to _ >> 1 (III).
Paramagnetic (C) should be aligned with 0 < _ < _ (IV).
Non-magnetic (D) clearly fits _ = 0 (I).
Therefore, the correct answer matches:
A-II, B-III, C-IV, D-I.
This aligns with Option A .
