How Are Debye Length and Ohm's Law Related?

AI Thread Summary
Debye length is a measure of the distance over which electric fields influence charge distributions in a plasma or electrolyte, while Ohm's Law describes the relationship between voltage, current, and resistance in conductive materials. The Poisson-Boltzmann equation, which incorporates Debye length, helps explain how charge distributions affect electric fields, providing a foundation for understanding conductivity. The connection between Debye length and Ohm's Law lies in how the spatial distribution of charges influences the overall conductivity of a medium. Understanding this relationship is crucial for applications in electrochemistry and plasma physics.

Hello, I am new here.
I was reading Wangsness electromagnetic fields and he delves into a short discussion about poisson-boltzman equation/Debye length before introducing the point-form of Ohm's Law. Just wondering what the significance of this was and how these two things are related.

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...
