Domain formation is the necessary feature of:
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.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
