Above Curie temperature:

Question

Accepted Answer

1. **Curie Temperature ($T_c$):** The magnetic properties of ferromagnetic materials are dependent on temperature. The Curie temperature is a critical transition temperature specific to a ferromagnetic substance.
2. **Mechanism:** In the ferromagnetic state, atomic dipoles are aligned in macroscopic domains. As the temperature increases, thermal agitation competes with this domain alignment.
3. **Transition:** Above the Curie temperature, the thermal agitation becomes sufficient to disrupt the ordered domain structure. Consequently, the material loses its spontaneous magnetization and transforms from a **ferromagnetic** state to a **paramagnetic** state .
