In regards to the famous experiment where a magnet is put under a sheet of paper with iron shavings on top, i don't understand why they distribute according to the shape of the magnetic lines of flux. (as seen in the link below)

I'll explain the way I am thinking of it so someone can correct me.
I imagine a magnet as giving off a fixed vector force in all directions, and that the magnitude and direction of the vector at any point is dependent on proximity to the negative/positive poles.
So when you dump the iron shavings over the magnet, i don't understand what causes them to gravitate to these specific lines, and why there would be gaps without shavings between the flux lines.
I imagine the distribution of the iron shavings to be relative to the magnetic vector frce applied to them from where they land.
