The electrons on the metal globe of a Van De Graaf Generator gather on the outside surface of the globe. It is universally held that this occurs because the electrons are all trying to get as far away from each other as possible. This is absurd! Why would the electrons on one side of the metal ball be so "eager" to get as far away as possible from the electrons that are located on the other side of the globe, many inches away from it, yet, they seem to have no problem crowding together on the surface of the metal ball???!!!
I think I can explain this! When electrons travel in opposite directions in two parallel wires, they do not repel each other. Instead, they are drawn together. Likewise, if electrons are spinning in the same way (all clockwise, or all counter-clockwise)--they can draw close to one another. The faster they spin, the closer they can get.
Of course, this would also cause a magnetic effect perpendicular to the metal ball.
This also might explain why metal balls can be "positively" charge, and seemingly, the "positive" charges still gather at the surface of the metal ball. Since protons are almost certainly not mobile, it makes more sense to suppose that the "positive" charges on the surface of a metal globe are oppositely-spinning electrons!
What do you think? Would you please be so kind as to forward this to anyone whom you think might be interested!
