← ScienceWhich outcome occurs when ferromagnetic core particles within an inductor experience high frequency magnetic field reversals?
A)Increased inductor saturation current rating
B)Reduced inductor core eddy current losses
C)Elevated inductor core hysteresis losses✓
D)Improved inductor temperature coefficient stability
💡 Explanation
Increased frequency causes more rapid magnetic domain wall motion, leading to increased energy dissipation via hysteresis; therefore, core hysteresis losses increase rather than decrease, because the core material is constantly re-magnetized.
