← ScienceWhich mechanism causes magnetic domain alignment under coercive force?
A)Hysteresis overcomes thermal energy✓
B)Superconductivity excludes magnetic field
C)Piezoelectricity produces lattice deformation
D)Resonance amplifies magnetostriction effects
💡 Explanation
Applying a coercive field promotes domain alignment via domain wall motion overcomes thermal energy. Therefore net magnetization increases because hysteresis prevents immediate randomization, rather than other electromechanical or quantum effects under these conditions.
