Positive and Negative Van de Graaff Generator Experiments

[@felixmeyer1972]

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.

[@UtkarshRana9999]

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

[@Ham549]

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

[@redoverdrivetheunstoppable4637]

yeah, i expected that

[@alexanderyang8720]

Yeah what's going to happen?

[@kerem4152]

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?

[@Ricardo-qe2qx]

Coca-Cola and Pepsi working together for the world.

[@nickbaylander6320]

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

[@vineethvenugopal8613]

It is because of the roller materials and the way we keep them. The electrostatic charge produced as a result of friction depends on the nature of materials. Some materials acquire positive charge and some acquire negative charge. In the 1st one, the top roller is nylon and the bottom roller is silicone . In the second one, it is the exact opposite. That's why they are opposite in charge.

[@fh64lucky]

@@vineethvenugopal8613 I made one with glass tube on bottom, pvc on top and rubber belt, it works well, why does it matter if positive or negative?

[@robson6285]

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

[@TechnoW1zard]

Schematic for the polarity detector please?

[@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).

Swap the rollers

[@sebaberny7170]

@@mackroscopik for me is not clear :) The reversing of the motor rotation have the same effect of a 180° rotation of the device itself.. or not?

[@pneumatonic]

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. F.

[@ridefast0]

To reverse the polarity, you can use the same belt material but you must reverse the top and bottom pulley materials.

[@hubb8049]

@@ridefast0 rollers?

[@ridefast0]

@@hubb8049 yes, the rotating surfaces which touch the belt.

[@mykulpierce]

Am I correct in assuming that you can control the pulses by changing the Dynamics of the wheel such as diameter or number of balls?

[@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?

[@johnnewman3221]

will the negative generator attract or repel objects

[@mackroscopik]

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

[@NiGMa46]

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 charge?..... right?

[@batenkait0s657]

if you consider that your neurons use electrical signals and note that electric eels just use pumped up versions of our metabolism it should be pretty clear that we humans have a charge not to mention the electrolytes like sodium calcium and potassium that we use

[@davidkempton2894]

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 😊

How you produced negative charge on belt

[@Fil_electret]

The electrostatic motor will also work if you make two generators, such as positive charges. But generators must be different in size (power). Try it works!

[@Paruthi.618]

How you get nylon roller

[@CondensedComments]

This is cool! If we truly wanted to validate which was an excess of electrons and which was a deficiency, we could watch the direction of flow with a large enough gap and high speed film. Excess electricons should cause a spark to jump from the contact to your hand (if you're earth/ground) and from your hand to the contact, if there's a deficiency.

[@Fact_GIF]

what is material of those rotating balls?

[@ThomasKim]

[@piyushtiwari7467]

Very good experiment

[@PinkeySuavo]

omg in 3:30 i was kind of sure they are speeding up because of that effect when speed of rotation is becoming a multiple of FPS value, and in reality they really slowed down :D I also had a brainlag and didn't see u're discharging cans.

Really cool stuff 😎

[@svenpetersen1965]

Cool video. Very interesting. I have already built a Van-der-Graaf generator with pvc and glass rollers and a steel ball from the garden market. It could build up way higher voltages than with the coke can, that I was using before. I am still loosing charges at the edge, where I have cut the ball open, but I think, I have found a solution for that. I need to round that edge. BTW, what is that charge indicator?

[@Alpha_Gadgets-360]

Bro please reply me i want to make it as a college project

[@Alpha_Gadgets-360]

Can u share details on my WhatsApp or insta

[@svenpetersen1965]

@@Alpha_Gadgets-360 it all depends on which materials you can get. There are many ways to built a van de Graaff generator. As a glass roller, I have used the glass from a fuse, that I have put on an M3 threaded rod. I used a 5cm water pipe as a column and a ball pen refill and a pvc sticky tape. The convexity (thick in the middle, thin at the ends) of the driving axis isa key feature, that keeps the rubber band in the middle. YT is full of tutorials, I think. Humidity is not your friend. I am using a latex band and it seems, that it absorbs moisture. And that prevents the generator from working. It is possible to dry the band with a hair dryer. It is also helpful to watch the generator in the dark. You can see, if/where the charges escape. Sharp edges are the problem. That is, where the electrical field is strongest. If it is your school project, you should make sure, that you have understood how the generator works. Triboelectric effect is the keyword. You have two different roller pairs: pvc/latex (bottom) and glass/latex (top). As charge collectors, I have used the „hair“ of a brass brush. It can also be wire strands from a cable. You want it to have many points, because the electric field is strongest on a pointy surface. This way, the charges will jump to the collector. The collectors should be very close to the rubber belt, but not touching.

5:14 WHAT THE FU.. happened there

[@redoverdrivetheunstoppable4637]

i'm not sure bcs the movements were confusing at some point but the idea is apparently that if you get a can close to a charged pole without sparking, it charges with the opposite polarity, he touches the free can to provide a bigger path to the ambient so it charges kinda like a capacitor... not sure, but it seems

[@haydenwhitbread724]

Positive can has a lack of electrons. Extra electrons make their way into the green can since they all want to get over to the red can (from air and other surfaces it touches. If there is no discharge, green becomes negatively charged due to the extra electrons.

[@haydenwhitbread724]

When you see the arc, that pent up electric charge (extra electrons) is free to move to the red can and the red cans "thirst" is mostly satisfied but the motor in the van de graaff rubs two materials that continuously removes electrons from the red can and it becomes highly positively charged again.
