- high retentivity and low coercivity
- high retentivity and high coercivity
- low retentivity and high coercivity
- low retentivity and low coercivity
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
To make permanent magnets, a material should have high retentivity, which ensures that the material can retain its magnetization, and high coercivity, which means the material resists being demagnetized. These properties are ideal for permanent magnets.
