Links and discussion about electrostatics/static electricity (high voltage charge), electrodynamics and related things. The electric force is the simplest, most direct and most powerful force.

Electrostatics is the class of phenomena recognized by the presence of electrical charges, either stationary or moving, and the interaction of these charges, this interaction being solely by reason of the charges and their positions and not by reason of their motion.

Wireless electrostatic hair integration

Can someone help me with my project I'm looking for talented freelancers to collaborate on an exciting project involving hair integration technology. The project focuses on using electrostatic principles to enhance hair integration in wigs, and I need skilled individuals who can contribute to various aspects of this innovative concept. What am looking for Skills needed: Experience in electrical engineering or related fields Knowledge of electrostatic charging mechanisms Familiarity with Bluetooth technology and integration Creative problem-solving skills Project Overview: • The project involves developing a system that allows hair to be charged and integrated into wigs seamlessly. • I'm particularly interested in exploring both external and integrated charging mechanisms. Next Steps: If you're interested in learning more about this project, please reach out! I'd love to discuss the details further, but I will require a signed NDA before sharing specific information. Thank you for your time, and I look forward to connecting with potential collaborators!

Electrostatics and the Periodic Table

Here is one of several peer-reviewed papers concerning some work I did on the subject of electrostatic properties of electrons distributed in a spherical quantum dot as well as on a mathematical unit sphere (in free space). I discovered a connection between the energetics of the problem and the distribution of the "outermost" electron orbitals of atoms throughout the periodic table.

The latter problem, of electrons optimally distributed on the unit sphere, is called the Thomson problem because of its relationship to the 1904 classical electrostatic model of the atom proposed by JJ Thomson.

I'm posting this here both to inform this small electrostatics group of the work in case someone is interested in this area and to see if anyone may have some constructive feedback. I realize that the broader culture of electrostatics-interested scientists and engineers is concerned with electrostatic properties of macroscale objects constituting the charge of so many electrons (typically) that we treat these objects as sheets of continuous charge, but is there interest in nanoscale systems of few charges here?

An instructive, large poster I created a decade ago to summarize my thoughts on the subject is also available on the INTERNET Database of Periodic Tables (curated by a university professor). There's a large PDF of my work here for anyone interested in this new body of work:

What is the Difference between using Metal and Dissipative material ESD Pads

I am trying to currently figure what the difference between using a Dissipative ESD pad on a Work Bench versus a Work Bench that has a grounded thick metal plate on it that also has an input for an ESD wrist strap to ensure a technician is also properly grounded while working. I do understand the difference in resistance between the two materials results in any current that flows through them to react differently. I want to know if you are actively working on a circuit card is there a difference in protection from damage caused by ESD between these two.

I turned on the apparatus, and it does in fact produce static electricity.

I made it a little wig, and I can feel the zappers zapping. Still not sure what all it does. The box it came in has an assortment of metal plates and glass rods. Going to keep experimenting with it.

Can someone tell me what this is?

I found this at an antique store, and picked it up because it looked interesting. I haven’t tested it out yet. The only info I have is the nameplate that says it’s a piece of navy instructional equipment for electrostatics. Any help would be awesome.

Issues With Calculating Repulsive Electrostatic Force

Lets say I charge 2 metal plates positively with 15,000V of electricity. How can I calculate their repulsive force using their area (which is 1m^(2)), and their seperation distance (Which is 0.1 m)? What I don't understand is that the capacitance between the two plates does not matter (because they are both charged equally), so how can I calculate the charge that will accumulate? I am suspecting that it may be parasitic capacitance, and if so, how can I increase the repulsive charge through the capacitance? I understand that voltage plays a significant role, however at 15,000V I should be able to accumulate any amount of charge as long as I increase the capacitance.

Hypothetically(and thats being generous) If two objects with high amounts of static electricity / Magnetic force rotate and a rate equal to the visible spectrum, would it give off visible light?

This would be done in a hyper-cold vacuum to try and avoid any heat buildup giving off light.

Obviously this isnt possible with modern technology as far as I am aware. So this is purely hypothetical.

Thanks!

Can you charge the sphere of a van de graaff generator negativ ?

Hi guys,

I have found this hoover that uses the principle of a van de graaff generator. Normally the generator generates positive charges in the sphere. My question is... if you change the triboelectric materials of the rollers... can you charge the sphere negatively to attract positively charged dust?

Wimshurst machine not working

Hello!

So I recently built a Wimshurst machine for my school project, but it doesn't seem to be working.

There is some arcing/corona at the neutralizer bars, but I'm quite sure that the problem is the collector comb.

I used a solid copper wire and filed it down to be sharp, but would attaching smaller wires (very thin) work better as a collector?
