Hello, i'm trying to understand what represents the rotational. On wikipedia I saw that for a vector field F it gives the rotation axis of F at the point (x,y,z), but I don't undersand how the formula
can give me this rotation axis, how can i interpret this formula?

I believe that means that the rotation of F equals the wedge product of the gradient and field, thus the rotation is defined as the perpendicular to the gradient on F? Hmmm, I am not sure that is too helpful, I am not too versed in this sort of thing? Try looking at: Applet: A rotating vector field - Math Insight, perhaps that will help you? Best of luck!
