Is gravitation an independent force? Or is it "only" some "special" version of electromagnetism? Have you ever thought about why gravitation has a long-distance effect? Why do the weakest of the fundamental interactions have long-range interaction? Why do other natural forces like strong-nuclear force have only a short-distance effect? And why the distance of the fundamental interaction increases when the scale of the effecting particles increases? The strong nuclear force affects only on the scale that is smaller than proton or neutron. But the electromagnetism effects also between the atomic groups. The difference between electromagnetism and gravitation is neutral. Gravitation is the non-polar force that effect is not depending on the poles of the particles. The electromagnetism pushes and pulls the objects depending are the same poles opposite together. The thing that causes the pulling is the electron flow and electromagnetic fields around the magnets.
