Iron loss in a transformer consists of hysteresis and eddy current losses, both of which are dependent on the supply frequency. As the frequency increases, the hysteresis loss increases because it is directly proportional to the frequency. Similarly, eddy current loss increases with the square of the frequency. Therefore, increasing the supply frequency to a transformer will increase the iron loss.

If the Supply Frequency to the Transformer Is Increased,"the Iron
