Answer 2

The right answer to the given question is option d: Alnico.

• Permanent magnets are materials having a high retaining power of magnetic moments of their constituent atoms and the ability to demonstrate magnetism without the help of any outside influence.
• A ferromagnetic substance, which has the property of iron to exhibit strong net magnetism is one of the materials that have this feature.
• As a result, Alnico is utilized to make permanent magnets because it possesses strong ferromagnetism characteristics.
• Alnico is a mixed alloy including iron as the major element and other elements such as aluminum element, nickel element, and copper element.
• Because of its strong property depicted above, it is utilized to make permanent magnets.
