← ScienceWhich phenomenon limits magnetic flux density in transformers?
A)Spontaneous magnetic domain alignment✓
B)Thermal runaway of the windings
C)Eddy current hysteresis losses
D)Magnetostriction energy dissipation
💡 Explanation
The maximum flux density is limited during ferromagnetism because spontaneous magnetic domain alignment causes magnetic saturation, therefore flux increases minimally rather than proportionally with current, affecting core efficiency.
