⚡ Enter ArenaAn engineer observes that as a magnetic material approaches its Curie temperature, the magnetization decreases continuously to zero. Which mechanism explains this behavior?
A)Increased domain wall pinning impedes reversal
B)Magnetostriction effects dampen thermal fluctuations
C)Thermal energy disrupts long-range order✓
D)Quantum tunneling spontaneously demagnetizes domains
💡 Explanation
As temperature nears the Curie point, increased thermal energy disrupts the cooperative alignment of atomic magnetic moments that gives rise to long-range ferromagnetic order, because the energy overcomes the exchange interaction. Therefore, the magnetization decreases to zero, rather than remaining stable or increasing due to other effects.
