← ScienceWhich risk increases when a strong external magnetic field opposes a ferromagnet's existing magnetic domains?
A)Hysteresis loop energy dissipation increase✓
B)Curie temperature limit reduction
C)Spontaneous magnetization domain growth
D)Bloch wall permeability stabilization
💡 Explanation
Increased energy dissipation emerges from domain wall motion caused by the reversing field attempting to re-align the atomic dipoles via the Landau-Lifshitz damping mechanism; therefore hysteresis losses increase during each cycle rather than stabilizing or decreasing. Therefore, Curie temperature nor Bloch wall permeability apply here.
