- Cunife
- Tungsten steel
- Supermalloy
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Magnetic materials are classified as:
• Soft magnetic materials → low coercivity, easily magnetized/demagnetized
• Hard magnetic materials → permanent magnets
Step 1: Evaluate options.
• Alnico → hard magnetic material (permanent magnet)
• Cunife → hard magnetic alloy
• Tungsten steel → hard magnetic behavior
• Supermalloy → very high permeability, soft magnetic material
Step 2: Final selection.
Supermalloy is used in:
• transformers
• magnetic shielding
• low coercivity applications Final Answer: \[ \boxed{\text{Supermalloy}} \]
