Curie temperature of iron is the temperature below which it is:
Correct answer: B. Ferromagnetic
- A. Diamagnetic
- B. Ferromagnetic
- C. Low retentivity
- D. Both (a) and (c)
Explanation
The Curie temperature is a critical point for magneticmaterials. Below this temperature, a material like ironexhibits strong ferromagnetic properties; above it, thermalagitation overcomes the magnetic alignment, and itbecomes paramagnetic.
