Modelling Charged Particle Flow

SUMMARY

This discussion focuses on modeling the flow of electrically charged hydrogen gas in response to an electrostatically charged metal grid. The user intends to implement a simulation using a programming language that calculates forces based on Coulomb's law, updating every millisecond for precision. The primary inquiry is whether Coulomb's law suffices for modeling particle interactions or if additional calculations, such as magnetic fields, are necessary for accuracy. The consensus indicates that while Coulomb's law is essential, considering magnetic fields may enhance the simulation's realism.

PREREQUISITES
  • Coulomb's law for electrostatic force calculations
  • Basic programming skills for simulation development

I'm working on something right now where I want to model the flow of an electrically charged gas (hydrogen) reacting to an electrostatically charged metal grid.
I know, more or less nothing about this type of mechanics, so I want to create a model using a simple programming language, with a series of points arranged like the structure of the grid to simulate it, and other points traveling towards the grid at a high velocity to simulate the charged particles.

I was thinking I could set the program to calculate the force using Coulomb's law every milisecond (or faster for more precision) and use force vectors to calculate the motion of each simulated "particle".

To model how the charged particles interact with the charge of the metal grid, is Coulomb's law the only calculation I need to run for each particle at each moment, or do I need to also calculate the structure of the magnetic fields and other factors using more equations, to accurately plot how the charged gas particles respond?

Thanks in advance for any replies.

So your metal grid Just has an E field and no B field.
