← ScienceWhich magnetic domain outcome occurs within a ferromagnetic material exposed to an external field above its Curie temperature?
A)Net magnetization disappears completely✓
B)Domains align to amplified field
C)Domains stay frozen and locked
D)Giant magnetoresistance gets strengthened
💡 Explanation
Above the Curie temperature, the thermal energy disrupts the exchange interaction, because magnetization decreases; therefore, net magnetization disappears rather than alignment or freezing of domains, since the material transitions to paramagnetic.
