MCQ
Pick out the temperature at which iron becomes paramagnetic?
- A800°C
- B700°C
- C600°C
- D500°C
✓
Answer
- 800°C
Explanation:
Iron is a ferromagnetic material. Ferromagnetism decreases with a rise in temperature, and above a certain temperature called “Curie’s temperature,” ferromagnets become paramagnets. For iron, it is approximately, 800°C.
