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.

I don't know how to do anything?

Is this a homework problem?

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.
