    Em Field
In summary, the speaker is working on a hobby project involving manipulating top load streamers using EM fields. They plan to use a polished aluminum spherical top load and half of a Halbach sphere created with electromagnets to increase the field strength. They are aware of the limitations of their power supply and layout and are unsure if the EM field will disperse or be directionalized beyond the Halbach array. They also mention using a cylindrical Halbach array or wiggler magnets as potential solutions.

Hi all-
I am working on a hobby project to manipulate top load streamers by applying EM fields to the top load. I cringe to reference it, but think of Red Alert 2 on a much, *MUCH* smaller scale. The streamers are roughly 295KHz at 300kV (9kVA NST supply, 8.5turns primary coil & 1042turn secondary) and very low current due to the nature of a Tesla Coil, and I intend to use a polished aluminum spherical top load, r=3".

This is more theoretical than anything right now, but I am looking to use half of a Halbach sphere , but create the sphere using electromagnets rather than solid state, so I can scale the field strength up, rather than having a static field strength.

I understand the limitations of my relatively small power supply (experiencing only ≤8" streamers currently) and sub-optimal layout (1/4" copper tubing for primary coil).

I suppose my question is this: Will the EM field generated by the coil disperse as soon as it extends beyond the Halbach array, or will it be directionalized any significant distance beyond it?

My intuition is pushing me towards it dispersing like a trumpet bell as soon as it passes beyond the array (even if I were to use a cylindrical Halbach array in conjunction with the half-spherical), rather than acting more as a free electron laser, also using a Halbach array with a top layer to create wiggler magnets.

Pre-emptive thanks, and please provide ideas for other solutions!

I forgot to mention that I'm using a Tesla coil in the first sentence... My apologies.

Anything? By anyone?
 

1. What is EM Field directionalization?

EM Field directionalization refers to the ability to manipulate and control the direction of an electromagnetic (EM) field. This can be achieved through various methods, such as using specialized materials or devices, to alter the propagation of EM waves.

2. Why is EM Field directionalization important?

EM Field directionalization is important because it allows for targeted and efficient transmission of EM waves. This is useful in various applications, including communication, imaging, and energy harvesting.

3. How is EM Field directionalization achieved?

EM Field directionalization can be achieved through different techniques, including using antennas, metamaterials, and phased arrays. These methods involve controlling the properties of the EM waves, such as their polarization and phase, to steer them in a desired direction.

4. What are the potential applications of EM Field directionalization?

There are numerous potential applications of EM Field directionalization, such as in wireless communication systems to improve signal strength and reduce interference, in radar systems for target detection and tracking, and in solar panels to increase energy efficiency.

5. Are there any limitations to EM Field directionalization?

Yes, there are limitations to EM Field directionalization, such as the loss of signal strength and increased complexity with longer distances and higher frequencies. Additionally, the use of EM Field directionalization may also be limited by regulatory constraints and technical challenges.
