← ScienceWhich consequence results when exceeding the Curie temperature?
A)Loss of spontaneous magnetization occurs✓
B)Increased Hall effect susceptibility forms
C)Reduced magnetostriction causes lattice shift
D)Enhanced eddy current density concentrates
💡 Explanation
Heating a ferromagnetic material above the Curie temperature causes loss of spontaneous magnetization via disruption of the spin alignment, because above this temperature, thermal energy overcomes the exchange interaction. Therefore, spontaneous magnetization vanishes, rather than causing heightened magnetic behavior at that critical point.
