Magnetic Material Classification and Examples
This question requires matching different types of magnetic materials with their respective examples. We will analyze each category from List-I and find its correct match in List-II.
Matching Materials and Examples
- A. Diamagnetic Materials: These materials are weakly repelled by an external magnetic field. Examples include Bismuth (Bi), Copper (Cu), and Lead (Pb). Therefore, A matches with III.
- B. Paramagnetic Materials: These materials are weakly attracted by an external magnetic field. Examples include Aluminium (Al), Sodium (Na), and Calcium (Ca). Therefore, B matches with I.
- C. Ferromagnetic Materials: These materials are strongly attracted by an external magnetic field and can retain magnetization. Examples include Iron (Fe), Nickel (Ni), Cobalt (Co), and alloys like Alnico. Therefore, C matches with IV.
- D. High temperature superconductors: These are materials exhibiting superconductivity at temperatures significantly above the boiling point of liquid nitrogen. Examples include $\text{SrTiO}_{3-x}$, $\text{LiTi}_{2}\text{O}_{4}$, and $\text{Ba}(\text{Pb, Bi})\text{O}_{3}$. Therefore, D matches with II.
Correct Matching Combination
Based on the analysis, the correct matching is:
- A - III
- B - I
- C - IV
- D - II
This corresponds to option 3.
