At around 770 °C, iron (Fe) reaches its Curie point: the critical temperature at which it transitions from a ferromagnetic to a paramagnetic state (and vice versa). Below this temperature (770 °C ≈ 1043 K), iron’s atomic magnetic moments align within regions called magnetic domains, resulting in strong, permanent magnetism. However, when heated above the Curie point, thermal agitation disrupts this alignment, and iron loses its ferromagnetic properties, becoming paramagnetic. Iron is a classic e
