The role of the iron core

The actual transformer always operates in the alternating current state, and the power loss is generated not only in the resistance of the coil, but also in the core under the magnetization of the alternating current. The power loss in the iron core is usually called "iron loss", and the iron loss is caused by two reasons, one is "hysteresis loss" and the other is "eddy current loss".

Hysteresis loss is the iron loss caused by the presence of hysteresis in the process of magnetization of the iron core, and the magnitude of this loss is proportional to the area surrounded by the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of the core of the transformer is small, which can greatly reduce the degree of heating.
