But you don’t see it. You misunderstand what the field lines show. [...] You can’t draw conclusions about attraction or repulsion between the magnets from the lines or null areas.

From the poles as well. As you see with both iron filings and nano-size iron particles in ferrocell, repulsive vector between like poles along diagonal is at 45˚ to magnets with like poles facing one another. That can be reproduced by moving two magnets facing one another up and down respectively, to mirror 45° angle in magnets side-by-side.

You are repeatedly ignoring the fact that neither the iron filings nor the ferrocell show repulsive vectors - read what the inventor says.
I suggest you find a probe Gauss meter and do some actual measurement. PM me when you’ve done that and we’ll continue this topic
