Question
Curie temperature is the one above which
- Paramagnetic substance changes of ferromagnetic
- Paramagnetic changes to diamagnetic
- Diamagnetic changes to paramagnetic
- Ferromagnetic changes to paramagnetic
The correct answer is: Ferromagnetic changes to paramagnetic
The curie temperature or curie point of a ferromagnetic material is the temperature above which it looses its characteristic ferromagnetic ability to possess a net magnetization in the absence of an external magnetic field. Hence, above curie temperature material is purely paramagnetic.
