← ScienceWhich risk escalates when exceeding a ferromagnetic shielding's saturation limit?
A)Hysteresis losses increase significantly✓
B)Complete magnetic field expulsion
C)Meissner effect diminishes rapidly
D)Curie temperature decreases sharply
💡 Explanation
Exceeding saturation induces higher hysteresis losses of external magnetic fields because domain wall motion becomes irreversible, therefore shielding fails rapidly rather than expelling all magnetic flux even at lower strengths.
