Electrostatic Charge: Chemical Polarity & Charging Materials

AI Thread Summary
Dust particles can indeed be charged, regardless of their chemical polarity. Charging occurs through various mechanisms such as friction or contact electrification, not solely based on a material's chemical properties. While chemical polarity can influence how materials interact with electric fields, it is not a prerequisite for charging. Therefore, the assertion that dust cannot be charged due to a lack of chemical polarity is incorrect. Understanding the principles of electrostatics reveals that many non-polar materials can still accumulate charge.

Someone told me that dust can not be charged becuase it does not have chemical polarity.
Is that right?
Should materials have chemical polarity to be charged?

Dust particles can be charged, and this is completely independent of their chemistry.
Who is "someone"?
 
someone is my friend and he is studying civil engineering
 

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...
