Question:
Which of the following materials is the most suitable for making a permanent magnet?
Which of the following materials is the most suitable for making a permanent magnet?
Show Hint
For permanent magnets, always choose a material with high retentivity and coercivity — like steel.
Updated On: Jun 12, 2025
- Soft Iron
- Nickel
- Copper
- Steel
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Steel is the most suitable material for making a permanent magnet because it has high retentivity and coercivity, which means it can retain its magnetism for a longer time once magnetized.
Soft iron, though easily magnetized, quickly loses its magnetism.
Soft iron, though easily magnetized, quickly loses its magnetism.
