from low load trials of a 400 kW inductor. The results of numerical simulations, such as the temperature and Joule heating rate, show reasonable correlation with experimental data. The results indicate that Joule heating rate and the temperature reach the maximum at the corners and the minimum at the centre of the cross-section area. The temperature difference between the inlet and outlet......
