← ScienceWithin an inductive heater using a ferromagnetic core, which outcome arises should the Curie temperature be surpassed during operation?
A)Hysteresis losses decrease significantly✓
B)Eddy current heating rises sharply
C)Gap reluctance suddenly declines
D)Skin depth abruptly diminishes
💡 Explanation
Approaching the Curie temperature, the magnetic domains randomize, because the thermal energy overcomes the exchange interactions maintaining alignment; therefore, hysteresis losses are dramatically reduced, rather than eddy current increasing, which requires higher rates of magnetic flux change.
