Correct answer: A. Ferromagnetism
- A. Ferromagnetism
- B. Paramagnetism
- C. Diamagnetism
- D. All of these
Explanation
Ferromagnetism is characterized by the presence ofmagnetic domains, which are microscopic regions where themagnetic moments of atoms are aligned. The alignment ofthese domains in an external field is what causes the strong magnetic properties of these materials.
