SUMMARY

Iron and steel lose their ferromagnetic properties when heated above the Curie temperature of 1043 K, which is significantly lower than their melting point of 1811 K. At temperatures exceeding the Curie point, these materials undergo a phase transition that prevents them from maintaining spontaneous magnetization. However, they can still exhibit paramagnetic behavior in the presence of an external magnetic field.

PREREQUISITES
  • Understanding of ferromagnetism and paramagnetism
  • Knowledge of phase transitions in materials
  • Familiarity with the Curie temperature concept
  • Basic principles of thermodynamics related to material states
NEXT STEPS
  • Research the effects of temperature on magnetic properties of materials
  • Study the phase transition mechanisms in ferrous materials
  • Explore applications of paramagnetism in engineering
  • Investigate the melting points and magnetic properties of other metals
USEFUL FOR

Materials scientists, physicists, and engineers interested in the magnetic properties of metals, particularly in high-temperature applications.

Is iron/steel magnetic at temperatures over their melting point? I have an idea, but it will only work if ferrous materials retain magnetic properties in a liquid state.
 
Physics news on Phys.org
Melting temperature of iron : 1811 K
Currie temperature of iron : 1043 K

From wikipedia:

"When the temperature rises beyond a certain point, called the Curie temperature, there is a second-order phase transition and the system can no longer maintain a spontaneous magnetization, although it still responds paramagnetically to an external field."
