Positive and Negative Van de Graaff Generator Experiments

Recently I made two kinds of Van de Graaff Generators.
One is Positive, another one is Negative.
The two are almost similar, but the Negative is faster in discharging.

Das ist eine gute "How to"-Anleitung. Interessant war die Verwendung von Isolierband für den Antriebsriemen und wie man es auf die Rollen legt. Danke für die Zeit und Mühe, diese Videos zu machen. Es hilft vielen Menschen und inspiriert sie, etwas aufzubauen.

This will be great for teachers at school ! Simple and effective, great work and thanks for sharing.

Can you put a tutorial on how you made the generator, I am trying hard to make one that works

Coca-Cola and Pepsi working together for the world.

Why not run them both at once so they arc to eachother.

with this treasure I summon, the big raga, the oppa stoppa...

Hi I have a question can you help me? What should we do if we want to produce a negative charge in the Van De Graaff generator?

[robson]

Wauw i must say that is genius! I am really impressed about the clever thinking and built of the two. Also that detector i find a great thing

Amigo, thank you for sharing this with us all.


By the way, how did you get both polarities -- is it a reversal of the material which comprises the moving belt?


Another nifty thing to explore is the effect of electrostatic polarity upon the surface of water. Using wires connected to your generators, you might note as I have that one polarity will pull the surface of the water up towards the wire in an antigravity manner. The other will push into and displace the surface of the water, leaving an indentation. A whole realm of new possibilities opens up with this.

What's making one positive and the other negative. Why arnt they both positive?

[ajangramdan]

Please, how to build the electrostatic polarity detector

[just_a_dragon]

You have nice designs shown in your video's.
Also learned something new about the electrostatic induction which I should have known already(especialy due to a theory I once wrote which also includes a effect like that), it's just such a thing you won't think of until you do think obout it(such a thing you see and kind of understand without noticing).

[davidkempton]

That was a really nice video. Thanks for sharing it. BTW where do you get the drive belts from? I would like to try and make one of your VDG generators 😊

[TechnoWzard]

Schematic for the polarity detector please?

[mykulpierce]

Glad to see another test. Are you developing these designs? They're very elegant in their simplicity. Well done!

[NiGMa]

Excellent video, especially the clear presentation. Everything makes sense for me except around the 2m mark, why does the neg charge cause a blink in the detector but the pos does not? It seems your body can take on more total neg charge than it can pos right?

[mackroscopik]

Where can I get one of those polarity testers that you have there? What's the official name of it?

[serdargers]

How can i load Van de graff Globe with negatively ? Please reply ASAP. Thank ur helping

[CondensedComments]

Awesome!!!!

How does the electrostatic motor work, is it connected to earth so that the spheres change charges or does the mere presence of the two fields induce spinning?
