← ScienceWhich mechanism diminishes magnetic ordering above the Curie temperature in iron?
A)Thermal energy disrupts spin alignment✓
B)Chemical bonds saturate magnetic domains
C)Crystalline defects block domain walls
D)Reduced pressure inhibits electron excitation
💡 Explanation
Above the Curie temperature, thermal energy disrupts spin alignment via the Curie-Weiss law, causing the loss of ferromagnetism because increased atomic vibration competes with spin coupling, therefore disrupting long-range order rather than chemical or crystalline effects which are secondary at this threshold.
