Which risk increases when a transformer core overheats?

💡 Explanation

Overheating risks loss of ferromagnetic domain alignment because the high temperatures disrupt the substance's magnetic ordering. Therefore, the response is demagnetization, rather than increased currents caused by changing resistivity at lower temperatures.
