Ahh I am such an idiot. I need a solonoid.

Well the issue is that for some reason I can't a simple electromagnet for sale that produces strong forces. Most of the ones I find are holding magnets. Similar to that of the cup formation /horse shoe. I need an electromagnet that is like that of a bar magnet

Yes this would be the case

the ones I bought do repel but its unstable since the poles are in the same plane. Imaging a cup where the outer rim is one pole and a center column is the opposite pole.

Sorry for the poor English. Say electromagnet #1 is fixed. I need to introduce electromagnet #2 whose say north pole touches the north pole of electromagnet #1 with a required force of 20 to 40lbf (this is a range of what's acceptable)

I also want to ask In this scenario it would be when the opposing poles are touching.

I need help find a electromagnet suitable for this http://imgur.com/a/vkm4T Each electromagnet (the 3 in the center) needs a repelling force of about 20 to 40lbf. I stupidly bought these from amazon http://a.co/aSftIat. Its a holding electromagnet so the N and S poles are essentially on the same...

Yes this might work. Currently looking for flex pcb vendors

Ozone production isn't necessary I just want to study the chemical species produced. I'm expecting there to be ozone and other oxygen allotropes. Is it not produced in dielectric barrier discharge? https://en.wikipedia.org/wiki/Ozone#Cold_plasma Also I the HV electrode shoould be around 5-10kV...

Well I haven't built anything but the original design is simply this https://imgur.com/a/DWoxQ, Where the horizontal wires has a HV signal, and the vertical wire is a grounded electrode. I just need an insulated version of this, as in the copper isn't being exposed.

Well when I inquired about the design to a pcb maker I asked if the grounded electrode can protrude from the surface. So there should be a cavity if its a square mesh correct? I like the PCB idea more than the pic I included. I have also thought about dipping the copper mesh in some kind of...

Yeah I just realized that. Just requested a quote from a flexible pcb maker, Im looking to achieve dielectric barrier discharge / ozone production

It needs to be flexible. I'm just trying to create surface discharge from a flexible medium.

I'm constructing a device that needs two electrodes in a mesh-like formation. there doesn't have to be a cavity but one is preferred. I have this https://imgur.com/a/DWoxQ But I need there to be insulation like on a normal wire. I'm looking at a wire gauge of 28+ AWG. Ive tried 3D printing a...

Check Google Patents. I've had a few good ideas myself and I always end up seeing that they've already been patented even though the idea doesn't come up on google search. Also If it involves "free" energy forget about it. Also you'll get more help if your more specific, "Physics" is a uh big...
