🔥 Curie Temperature of Iron
The Curie temperature of iron (Fe) is approximately:
770 °C (1,418 °F or 1,043 K)
📘 What Happens at the Curie Temperature?
Below 770 °C: Iron is ferromagnetic - it can be magnetized and exhibits strong magnetic properties.
At or above 770 °C: Iron becomes paramagnetic - it loses its permanent magnetism but still weakly responds to magnetic fields.
This transition occurs because the thermal energy at high temperature disrupts the alignment of magnetic domains in the material.
🧲 Why It Matters:
Material science: Important in designing magnetic materials.
Industrial processing: Must be considered in applications involving high temperatures (e.g., motors, transformers).
Physics: Demonstrates a key phase transition in solid-state physics.
