Curie temperature is the temperature above which:

1. ferromagnetic material becomes paramagnetic material
2. paramagnetic material becomes diamagnetic material
3. paramagnetic material becomes ferromagnetic material
4. ferromagnetic material becomes diamagnetic material

Correct answer: ferromagnetic material becomes paramagnetic material

Solution

The Curie temperature is the temperature above which a ferromagnetic material loses its ferromagnetic properties and becomes paramagnetic due to thermal agitation disrupting the alignment of magnetic domains.
