Just don't perpetuate the myth that magnetic field lines actually exist. It's just a model that we use to visualize fields. What you see in this video is magnetism induced in particles, then they stick together end-to-end in lines, then the lines repel each other. Not field lines

I know very well about the quantized field theory of EM. Though I do find your comment to be philosophically naive. The photon exchange you’re referring to is a model as well.

You might know it, but are you leading others to believe the myth with how you are describing this demo? Misconceptions are a pervasive and dangerous thing in science education.

You’re suggesting we teach QED to high schoolers .. or what? I’m struggling to see your point .. maxwells equations aren’t a misconception

What makes you think a virtual photon exchange exists more than magnetic field lines?

I never said any of those things. I said that you're perpetuating the myth that field lines are real. That's all. Magnetic fields are continuous, no lines.

i think i see what you're saying .. but still the lines do exist in R^3 even though there are an infinite number of them filling space
