Homework Help Overview

The discussion revolves around deriving a partial differential equation (PDE) related to the potential distribution in a stationary electrolyte influenced by a magnetic field and current density in a two-dimensional context.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to derive the PDE by balancing charges but expresses uncertainty about how to proceed. Some participants question whether this is a homework problem and if it is posted in the correct forum section.

Discussion Status

The discussion is in its early stages, with participants clarifying the nature of the post as a homework question. There is no explicit consensus on the approach to the problem yet.

Contextual Notes

There is a mention of a separate homework section in the forum, indicating a potential issue with the placement of the thread.

Summary:: partial differential equation (PDE) to describe the potential distribution φ in the system

Hey, I need some help with the following question:

We have a stationary electrolyte, a magnetic field "B" and a Current density "j" (2D).

Derive the partial differential equation (PDE) to describe the potential distribution φ in the system by balancing the charges first.

Yes. Is it in the wrong forum part?
 
Yes. There is a separate homework section. I have asked the moderators to move this thread over there.
