AI Thread Summary
The discussion centers on the feasibility of constructing a small EMP device with a limited area effect for robot construction purposes. Participants suggest researching "vircators" and "explosively pumped flux compression generators" as potential options. However, there are concerns about the practicality and cost of creating such a device, with some expressing skepticism about its feasibility. The idea is also humorously mentioned as a potential senior prank, highlighting the interest in the concept. Overall, the conversation reflects a mix of curiosity and caution regarding small-scale EMP technology.

Well, it's more or less for robot constructon thing. Does anyone know if it's possible to construct a small EMP device that'll only have a couple meters worth of area effect? If there is, any hint on how to do it, or how much it would cost? Everything that I've found so far includes some type of nuclear detonation...

Thanks :)

Try a web search for "vircator", and/or "explosively pumped flux compression generator". One link that looks reasonable is:

Thank you very much :)
Doesn't seem toooo feasible to make though =(
 
Oh! That would be the greatest senior prnak ever! hehe

Though rather expensive :P
 
Thread 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
I passed a motorcycle on the highway going the opposite direction. I know I was doing 125/km/h. I estimated that the frequency of his motor dropped by an entire octave, so that's a doubling of the wavelength. My intuition is telling me that's extremely unlikely. I can't actually calculate how fast he was going with just that information, can I? It seems to me, I have to know the absolute frequency of one of those tones, either shifted up or down or unshifted, yes? I tried to mimic the...
