Other configurations

There are a large number of possible configurations with the Planeterrella.

Everything is mobile : the electric duct can move on its axis and on its stem, the poles of the spheres can move up and down like the foot of an umbrella, we can naturally change the locations of the sphères, the gas pressure and the intensity of the electric current can change. Soon, the spheres will also rotate around their geographical axis and electromagnet will allow to change the magnetic field intensities. Thus, many observations can be made. We give some pictures in bulk. Most of them can be described using the previous pages, but some are completely original. Only the imagination limits us !
