← ScienceWhich outcome occurs within transformers using silicon steel cores when magnetic field frequency is high?
A)Increased core hysteresis losses✓
B)Reduced eddy current formation
C)Enhanced magnetic domain alignment
D)Decreased magnetostriction effects noticed
💡 Explanation
Increased hysteresis losses arise because rapid magnetic reversals require energy to overcome domain pinning; the energy dissipates as heat due to overcoming the ferromagnetic material's coercivity during the magnetization cycle. Therefore, hysteresis losses increase, rather than eddy currents diminishing under these conditions.
