History

Which consequence results from exceeding iron's Curie temperature?

A)Loss of its ferromagnetism
B)Decreased electrical conductivity
C)Increased tensile strength greatly
D)Formation of iron oxides rapidly

💡 Explanation

Reaching the Curie temperature causes iron to undergo magnetic phase transition, therefore losing its ferromagnetism, because thermal energy disrupts the alignment of magnetic domains driving paramagnetic response. Rather than increasing strength or conductivity, magnetic properties are lost near 770°C.
