The temperature at which ferromagnetic material can no longer be magnetized by the outside forces, is termed as the____________________?
Correct answer: C. Curie temperature
- A. Critical point
- B. Inversion temperature
- C. Curie temperature
- D. Eutectic temperature
Explanation
Curie temperature is the critical temperature above which a ferromagnetic material loses its spontaneous magnetism and becomes paramagnetic. The other temperatures describe phase equilibrium or thermodynamic property changes, not magnetic behaviour.
