Which effect results when a radio-frequency wave's peak power constraint is exceeded in a MRI machine's gradient coil?

💡 Explanation

Gradient coil overheating occurs because exceeding the peak power leads to excessive resistive heating; the *Joule heating* mechanism causes the coil's temperature to rise, therefore coil damage is the outcome, rather than improved imaging effects under safe operating parameters.
