PRESENTATION: Two thin aluminum sheets are placed in parallel and close to each other, and they can move slightly. Both sheets are connected to a battery, in a way that the current may run either in the same direction by both sheets or in different directions. In the first case, the repulsion between both sheets can be observed, while in the second case the sheets attract each other.
