We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I created an Ansys Maxwell and Icepak Two-Way Coupling analysis for 1cm of cable based on the video:
https://www.youtube.com/watch?v=4MWTGHqRpjk

With the Eddy Current solver, I achieved an ohmic loss of 0.27W and a cable temperature of 65 degrees Celsius. I was not satisfied with this result - it's a bit low. 
I tried an analysis in the Magnestostatic solver, where the ohmic loss was 0.51W - almost double that. Then the cable temperature was 85 degrees Celsius and that was the result I wanted.

Why are these results so different? I don't understand which one is correct and which solver should be used to model this cable. 

I need to ask for an AC current of 1662A and a frequency of 50 Hz. 

I have found several different articles in which the authors use either the Eddy Current or Magnestostatic solver for the AC, hence my doubts and questions.
