The iron core of a transformer is also a good conductor of electricity.
The relative motion of the sinusoidal electromagnetic field will cause stray currents to flow at random across the iron core.
These stray currents, referred to as swirling currents, cannot be channelled either in or out of the core structure to do useful work:
Instead, their presence creates additional heat in the core structure.
