Which consequence likely results when exceeding the Curie temperature within a SQUID magnetometer?

A)Persistent bias field emerges
B)Paramagnetic alignment disappears instantly
C)Ferromagnetism vanishes progressively
D)Superconducting state becomes unstable abruptly

💡 Explanation

Exceeding the Curie temperature disrupts the ferromagnetic domain alignment within a magnetic shield or component, causing the **loss of spontaneous magnetization**. Therefore, ferromagnetism vanishes progressively, rather than exhibiting an instanteous paramagnetism because the Curie temperature is a phase transition point.
