Question

What is Curie temperature of Ferromagnetic material?

Answer 1

Ferromagnetic materials:

• Ferromagnetic materials are those materials that are strongly attracted by the external magnetic field.
• In solid-state, metal ions of these substances are grouped together in small regions called domains.
• Each domain acts as a tiny magnet.

Curie temperature: Curie temperature is a temperature at which a ferromagnetic substance loses its ferromagnetism and attains paramagnetism.

Curie temperature of Nickel is$360°\mathrm{C}$ , Iron $770°\mathrm{C}$ and Cobalt $1121°\mathrm{C}$ .
