Electric field in a more difficult situation

AI Thread Summary
Calculating the electric field between two differently sized charged plates, particularly with a neutral conducting plate nearby, presents challenges due to the complexity of charge distribution. The induced charge on the larger plate is not uniformly distributed, complicating the estimation of the exact charge distribution. For identical plates, the calculations remain intricate, often relying on approximations suitable for large plates with a high area-to-perimeter ratio. The discussion emphasizes that precise calculations in this scenario are not trivial and require careful consideration of the geometry involved. Understanding these nuances is crucial for accurate electric field analysis.

Could someone give me any ideas on how to calculate the electric field betweet two different size charged plates? The situation sounds like this: a neutral conducting plate is put near a charged smaller plate.
Could I say that the induced charge on the bigger plate is uniformly distributed? Otherwise how could I estimate the exact charge distribution?

Can't say it is evenly distributed. The calculation is not trivial. Even for identical plates the calculations are difficult so expression you often see is actually an approximation for large plates (high area/perimeter ratio).
 

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
