The area of hysteresis loop is
Correct answer: C. Energy dissipation per cycle
- A. Magnetism
- B. Demagnetism
- C. Energy dissipation per cycle
- D. All of the above
Explanation
The area of the hysteresis loop represents the energy dissipated as heat due to internal friction during each cycle of magnetisation and demagnetisation. This phenomenon is tied to the resistive forces within the material. Magnetism and demagnetism are related concepts, but do not specifically describe the area of the hysteresis loop. 'All of the above' is incorrect because not all listed concepts are represented by the loop area.

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.
