Which risk increases when exceeding the design temperature of ferromagnetic cores within high-frequency power inductors?

💡 Explanation

Exceeding the Curie temperature leads to loss of ferromagnetic order via the Curie-Weiss Law, where thermal energy disrupts the alignment necessary for intrinsic ferromagnetism. The material becomes paramagnetic, therefore sharply reducing, rather than increasing, the coercive field and magnetic saturation.
