If you sprinkle iron filings on a paper held over a bar magnet you can see a indication of the magnetic field running from the south to the north pole of the magnet. What particles make up these so called lines of force?

No, they are massless and are known as the B field or magnetic field. Current flowing inside the magnet is responsible for the rise of the magnetic field. Maxwell's laws state this:
If there is a changing electric field present, it will generate a magnetic field.
If there is a changing magnetic field, it will generate an electric field.
Light waves are actually a combination of an electric and magnetic field that are perpendicular to one another.

No they are not electrons. The magnetic field is created by the orientation of electrons in the bar itself. The result is the field, which is basically an unseen force, unless you put something in that force that indicates it is there, like the iron shavings

They are not made up of particles in the current understanding of magnetism. They are caused by electrons, which spin in their orbits and create electromagnetic fields. They tend to line up parallel to each other, especially in ferromagnetic materials and so create a more intense field than in other materials.

It is not known for sure yet, but they're not made of electrons.
Thus one can visualize magnetic attraction and repulsion as streams of photons with their corkscrew shaped wave functions screwing into (attraction) or screwing out of (repulsion) each other. Now you can visualize that forces do indeed arise from an exchange of particles, or their wave functions. It has been suggested that these streams of virtual photons travel along the magnetic lines of force.

I have heard of "magnetons."
I don't think that there are particles, though, but EM waves, a consequence of electrons spinning in the same direction in magnetized material.

a moving charged particle is what creates the b-field or magentic field.
