However, this flux cannot close within the core and can only circulate along the same direction through the three core columns, exiting the core through oil and the tank before returning. Due to the significant magnetic resistance outside the core, the third harmonic magnetic flux is relatively small, and consequently, the third harmonic voltage is usually not more than 5% of the fundamental. However, the third harmonic magnetic flux can cause eddy current losses in metal structural components."}
