← ScienceWhich consequence typically increases given repeated magnetic reversals in magnetic storage media?
A)Increased domain nucleation sites
B)Elevated coercivity threshold
C)Accelerated superparamagnetic transition✓
D)Enhanced magneto crystalline anisotropy
💡 Explanation
Repeated magnetic reversals gradually reduce grain volume, encouraging the superparamagnetic transition because thermal energy overcomes magnetic anisotropy energy preventing stable magnetization. Therefore data corruption increases rather than other magnetic properties enhancing which requires larger domain sizes.
