Solution
Correct Answer:
Strong permanent domain alignment
- Definition: Ferromagnetism is the property of certain materials (like Iron, Nickel, Cobalt) to undergo spontaneous magnetization even in the absence of an external field.
- Domain Theory: These materials consist of tiny regions called domains where atomic magnetic moments are already aligned parallel due to exchange interactions.
- Effect of Field: An external field causes these domains to grow or rotate, leading to a massive net magnetization.
- Conclusion: They show strong attractive properties and can become permanent magnets through the alignment of these domains.
