Iron loss refers to losses inside the magnetic circuit. The loss of the magnetic circuit of the transformer is called iron loss because the magnetic circuit is mostly formed by overlapping magnetic conductive iron sheets. Copper losses are losses in the primary and secondary windings. The winding is generally copper wire, which has resistance and some loss due to the impedance of the alternating current, so called copper loss. The two are added together and converted into heat.
