When an AC voltage is applied to the primary winding (coil connected to the AC source) of the transformer, a concentrated, alternating electromagnetic field is generated in the iron core by the flow of current through the primary winding.
The generated electromagnetic field causes an alternating voltage to be induced in the secondary winding (coil connected to the electrical utilization-equipment load).
