Physics-Magnetic Properties of Materials
NEET Physics Magnetic Properties of Materials Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Hard Magnetic Materials | (i) Lodestone |
| (b) Maximum Dipole Moment | (ii) m max = (8.65 × 10 10 ) × (9.27 × 10 –24 ) |
| (c) Magnetisation in Domains | (iii) 8.0 × 10 5 Am –1 |
| (d) Alnico | (iv) Ferromagnetic Material |
A
a-i, b-ii, c-iii, d-iv
B
a-iv, b-ii, c-i, d-iii
C
a-iii, b-iv, c-ii, d-i
D
a-ii, b-i, c-iv, d-iii
Correct Answer
Option A
Detailed Explanation
Hard magnetic materials include Lodestone and Alnico, and the maximum dipole moment is calculated as m max = (8.65 × 10 10 ) × (9.27 × 10 –24 ). The consequent magnetisation in domains can reach 8.0 × 10 5 Am –1, making option A the correct choice.
