Hi Simon, You are right that since this is an experiment it would be best to set up proper controls and define a clear aim. I have attached a sketch of my proposed setup to help with my description of the experiment. Since the amount of charge I can accumulate will be a function of the...

No I'm not hiding anything lol that's what I'm doing. The central region could be and iron core or a permanent magnet, the idea here is to see if it is possible to create a magnetic field capable of saturating (or magnetizing) a core by essentially using physical forces to drive an electrostatic...

The idea is to try to create a strong magnetic field using a fluid rather than a solid conductor so as to magnetize a central region. The question is how can I create a net excess of electrons in the fluid so that the fluid itself has a net charge.

Well yes this is what I thought would be the case but I was not sure so I asked. Follow up question, what would be the best way to charge a fluid? Would a static electricity charging source work best, or is it possible to create a charge imbalance of the type I mentioned using a battery?

Hey, I've been wondering about the behavior of flowing charged particles lately. In particular, imagine that I have a tank of charged fluid. Lets assume this charge density is 1 C/cm^3. I then allow the fluid to flow through a pipe of 1 cm^2 cross-sectional area at a rate of 1 m/s. Thus there...

@Baluncore Yes you are right, the current rise is not instantaneous. I will try to make the simulation voltage driven rather than current driven to model the effects. Is this conductor saturation time the same as the L/R time constant? I have a spool of AWG#32 that I can use. Is it easier to...

Hey guys, I'm very sorry but I made a terrible mistake during my simulation and had the turns per coil hardcoded to 10 instead of N (turns per layer * layers) which explains why the inductance was so similar for all of the arrangements. I halved the dimensions of the coil to reduce the...

@zoki85 I have reduced the dimensions of the device and magnetizing region such that I only need a 380 A current, is it now possible? @berkeman I could theoretically go over that (lets say max 500μs). I can't give too many details as to why but for the purpose of my application I would like to...

Hi guys, thank you for the input. Sorry I didn't post more details, I have since modeled and simulated the device, and have attached some images to aid in visualization. In the first image I show a cut away of the geometry. In the center is a region to be magnetized. The four columns...

Hi everyone, my question is related to producing a magnetic field from an array of straight parallel wires. In my scenario, imagine the wires as being stacked into a regular array similar to the way a pile of lumber is usually stacked, so that the ends are exposed, eg: ====================...

Carl is right, AWG 40 breaks incredibly easily. 60% is also a more practical number, so multiply the result I originally gave you by 0.6 (or if using triangular packing, which I suspect is what it would come down to, divide by 0.78 then multiply by 0.6)

It depends on what you are pumping the water for. Are you using it to pump clean water to your crops? Or are you using it to get rid of dirty water? If the water you pump is dirty, something like a screw pump would be best. If its to pump clean water, then you can use something like a piston...

oh btw that's assuming rectangular packing, if its triangular packing then divide the result by 0.78

Turns = turns per layer * number of layers turns per layer = height / wire thickness = 4 mm/0.08 mm = 50 number of layers = (OD-ID)/(2*wire thickness) = (9.5-7)/(2*0.08 ) = 31.25 = 31 layers therefore, Turns = 31 * 50 = 1550

enthalpy, i know what you're working on is just the coil, but maybe what is most needed is a way to focus the field so that it is concentrated in select areas rather than something which hits the whole brain. perhaps look into some kind of wave guide or focusing device? It could also be...
