← ScienceWhich phenomenon causes reduced sensitivity when a magnetic shield saturates?
A)Reduced domain wall mobility✓
B)Increased spin wave resonance
C)Enhanced magnetostrictive coupling
D)Decreased Curie temperature gradient
💡 Explanation
Magnetic shields lose effectiveness due to domain saturation; the domain walls become pinned from increased field, therefore their ready alignment decreases and the shielding factor lowers, rather than resonance effects which weaken when the Curie point is reached at higher temp.
