Creating a 2-D Electrostatic Field

AI Thread Summary
The discussion centers on the feasibility of creating a 2D electrostatic field, referencing Feynman's lectures on the mathematical modeling of such fields. Participants acknowledge that while complex variables are used for mathematical convenience, the actual fields are real and can be approximated in 2D. There is a comparison made to graphene as a 2D material, suggesting the possibility of a similar 2D electric field. However, it is noted that both electric and magnetic fields can only be approximately 2D due to the inherent three-dimensional nature of our world. The conversation highlights the challenge of realizing true 2D electrostatic fields in practical experiments.

I've been reading the Feynman lectures in physics. In volume 2 chapter 7: http://www.feynmanlectures.caltech.edu/II_07.html he shows how to mathematically model a 2D electrostatic field.

Is it possible to create an experiment that behaves the same way even with the complex variables?

Thank you in advance

The complex variables are just a mathematical trick. The actual fields are real.

I understand that it is a mathematical formulation for 2D models, but could someone create a 2D electric field instead of a 3D one, like how graphene can be considered a 2D material.

Couldn't you just solve the Poisson equation in 2D with the appropriate boundary condition?

Zz.
 
Just as graphene is only approximately 2D because we live in a 3D world, electric and magntic fields can only be approximately 2D because we live in a 3D world.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
