Solution


Q.

Match List-I with List-II.                                                    [2024]

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

 

Choose the correct answer from the options given below:
1 A-II, B-III, C-IV, D-I  
2 A-II, B-I, C-III, D-IV  
3 A-III, B-II, C-I, D-IV  
4 A-IV, B-III, C-II, D-I  

Ans.

(1)

For diamagnetic materials, magnetic susceptibility is less than zero i.e., (-1≤χ<0).

So, A→II.

For ferromagnetic materials, magnetic susceptibility is large χ≫1.

So, B→III

For paramagnetic materials, the value of magnetic susceptibility is small but positive 0<χ<ε.

So, C→IV

For non-magnetic materials, magnetic susceptibility is zero.

So, D→I

Hence, option (1) is correct
