Orientation of coils in flux 2D

Hello.

I have some doubts about the orientation of coils in FLux 2D version 12.2 (it is an older version because it is a version that my university bought some years ago).
When we put positive orientation in face region of the coil, we can consider that the current is enter in the screen of my laptop and the negative the oposite?
Imagine if the left coil is positive and the right is negative, we can consider that the current is enter in the screen and return from the negative one (right coil)? In that case the magnetic flux assumes the anticlockwise?

My geometry is in the attachement, it is a transformer with separated coils.

 

Best regards.

    Hi Diogo Cardoso,

     

    Yes, when we put positive orientation in the face region of the coil, we can consider that the current enters in the screen of your laptop and the negative the opposite, if the coils have the same orientation in the circuit, as in the figure below:

    If you have the circuit as in the figure below, the positive and negative currents are set in the circuit, then you set the positive orientation for both face regions.

    Hi Alexandru, 

    in the first circuit that you're showing, i think that there is a mistake. Shouldn't one of the coils be rotated?

    Hi Tiago,

     

    Thank you!

    Yes, i put the wrong Figure. I made the correction.
