1. ### The owie stick

Never said it was practical. Just possable. The general theory is to make, the path, of least resistance between you and your target as small as possable. Ps, it is unfathomably dificult to shield something from an emp, faraday cages useful for small balsts, but givin enough energy you can...
2. ### The owie stick

One em em pulse is cheaper than an explosive. Look at it from all sides. 30 000 dollar high explosive, or a cheap electric pulse. You be the judge. "i can disable a tank from 100 yards with a grinade, or a tazer...
3. ### The owie stick

The idea is to send an em pulse to whatever you're trying to disable...........^2 Think outside the box.
4. ### The owie stick

I had a general idea back in the day dubed "the owie stick". after seeing the movie "district 9", about how the "lightning gun" the main character used would or could work in a real life situation. I looked at it as a big tazer and thought if you shoot multiple conductive darts, one right after...
5. ### Bitter magnet help needed.

plate thickness: 0.0135 in insolater thickness: 0.015 in angle of asent: now im not sure how to calculate angle, so i took a swing at it. thickness of plate plus insolater is 0.029in 0.029×0.0254 (inches to meter) = 0.0007366m = t right? we will call that the hypotnuse of a right triangle...
6. ### Does accelerating electrons give a higher voltage

the way im understanding how voltage works is how fast one coulomb is passing a point. so if i push more electrons passed a point, it actually gives it a higher voltage? that and, if i have a screen with a positive potential across it and an electron stream flowing towards it, would the stream...
7. ### Bitter magnet help needed.

That was what I was looking for. Thank you :D
8. ### Bitter magnet help needed.

Im going to use teflon sheets between the plates. At low voltages it should be fine. I should be more concerned with heat honestly, considering the high ampres ill be pumping into this thing
9. ### Bitter magnet help needed.

A bitter magnet is composed of stacked plates, not wire. I was asking if I have to take the plates thickness into consideration when calculating B field.
10. ### Bitter magnet help needed.

alright so i think ive got a pretty good handle on this, im looking for a proof read though. any acurate input is greatly appreciated :D Field intensity in teslas = (amps x turns)/coil area; ignoring coil length effects meaning B=μ0(Ni)/m^2 right? but my question is: dont i have to...
11. ### Physics/chem question

what if you use light, ie a laser to heat it. therefore having no physical heat sink to make the process slow.
12. ### Physics/chem question

so it just goes "poof"? then please explain why co2, when it sublimates, in a closed container creates pressure.
13. ### Physics/chem question

let me refine the question while letting you know i have the following in mind: if you put dry ice in hot water it bubbles more violently then in cold water. so the question is: if you could apply heat to the entire solid simultaneously therefore making it expand. would it be enough force to...
14. ### Physics/chem question

bare with me here, this is kind of a physics/chem question. if you had a chunk of dry ice (solid co2) at one atm and heat it rapidly enough so it expanded, how hard of a "push" would it make? D:
15. ### Bitter magnets

first off :O! and second ty for giving me hope sir. i got 150 amps out of a modded MOT and some grounding wire i picked up at home depot. 15 windings is too much, so ill try one large multi-stranded winding insted. amateur question: when you said "coil area" in the equation did you mean...
16. ### Question on enamel coating

i am winding a transformer rated for 150A or more, and i cant find wire thick enough, in my neighborhood, to fit the profile. i did find a shop that sells bare wire at 8awg. so i thought i could put an enameled coating on each winding as i wound it. ya dig? is there a commercial "lacquer" i can...
17. ### Bitter magnets

at the moment im only trying to make a penning trap. sounds trivial but its only part of a bigger project. i was going to use Y123 at first as a plate material, yea not to easy to get made >_> .... yea then i saw the penning design and how it uses copper and an efficient water cooling system...
18. ### Bitter magnets

anyone have equations for bitter magnets? or do i use the ones for solenoids? i need an electromagnet capable of 4T. that doesn't use super conductors >_> i have access to liquid nitrogen though.
19. ### Penning trap

i have a personal project that has been brewing in my head since high school. i want to make an electron trap that is capable of holding more than a few particles. a friend has been helping me research the capability of electromagnets and penning traps. according to...
