How can I control or focus a magnetic field?

AI Thread Summary
The discussion explores the potential of using magnetic fields to control and focus energy emitted from a handheld Tesla coil. The goal is to direct this energy along a cylindrical shaft, creating a concentrated effect similar to a stun baton or lightsaber. Participants note that using an iron-cored electromagnet would only generate a circular field, which would be inadequate for energy containment. There is a need for methods to compress the magnetic field lines to achieve the desired focus while also mitigating safety concerns, such as exposure to X-rays. The conversation suggests a creative application of these concepts in science fiction writing.

After I discovered that someone had made a handheld tesla coil (http://www.rmcybernetics.com/projects/DIY_Devices/plasma-gun.htm), I started thinking about the possibilities. For example, would it be possible to use a magnetic field(s) to control and focus the energy that is being randomly radiated from the coil? The application that I had in mind would be to focus the energy from the tesla coil along the outside of a cylindrical shaft as closely and densely as possible. Think stun baton meets lightsaber! If the shaft had an iron cored electromagnet it would only produce a circular field around the shaft that would not be sufficient to contain the energy; there would have to be a way to "compress" the field lines down as much as possible to focus the energy, not to mention to prevent being continuously x-rayed.

LOL. You might want to consider re-posting this in our Sci-Fi Writing forum. :smile:

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
