Sub-atomic forces

There are issues physicists don't really talk about quite often but in my opinion are quite important. For example why do sub-atomic particles have electrical charges. In atoms and ions, these charges are some of the forces which bind the sub-atomic particles together on an atom. Instead of electrical forces why not magnetic forces binding electrons in their orbitals.

Its just food for thought. I think a knew trajectory is needed in our general approach in studying what we don't know in physics.
