Which risk increases when a ferromagnetic core overheats?

💡 Explanation

The Curie temperature exceeding leads to loss of ferromagnetic properties because thermal energy disrupts the exchange interaction mechanism maintaining aligned magnetic moments; therefore, core demagnetization occurs, rather than enhanced hysteresis, eddy current reduction, or permeability.
