why is ferromagnetic material used in a power transformer core?

Ferromagnetic materials are used in power transformer cores because they have high magnetic permeability, which allows them to efficiently channel magnetic flux. This property minimizes energy losses due to hysteresis and eddy currents, enhancing the transformer’s efficiency. Additionally, ferromagnetic materials can be easily magnetized and demagnetized, making them ideal for the alternating magnetic fields present in transformers. Their ability to sustain a strong magnetic field contributes to the overall performance and effectiveness of the transformer.
