Electrostatic demonstrations: electrical field lines between two charged spheres, same polarity

Hello

Electrostatic demonstrations: electrical field lines between two spheres both with the same polarity.

DSC07356trim400x326

The electrical field lines between two equally charged spheres are visible through semolina grains in castor oil, which are in a massive plexiglass box.
After the experiment, the liquid can be stirred with the small white bar magnet, so that the semolina grains are almost in a random distribution again.

Best wishes

Physikfan
your self promotion is getting a little tiring.
Not only this thread but quite a few of your recent posts only have you replying

not good

one of two possibilities;

Physikfan is a maniacal poster - not likely due to content and location
or
folks on 4HV are not interrested in fundamental H.V. demonstrations and principles
and Physikfan will get bored of us and go somewhere that fundamental HV experimentation is actually performed,
or at least appreciated.
