Maxwells equation in cgs system

AI Thread Summary
The discussion centers on the formulation of Maxwell's equations in the cgs system, specifically addressing the presence of the speed of light (c) and the factor of 4π in the equations. The equations presented include the curl of H and E fields, as well as the divergence of D and B fields, highlighting the differences from previous studies. The user seeks clarification on how these equations are derived in the cgs system, noting the discrepancies with earlier versions that did not include these factors. References to Wikipedia pages on Gaussian units and extensions of the cgs system for electromagnetism are provided for further context. Understanding these adjustments is crucial for accurately applying Maxwell's equations in the cgs framework.

hi, I have just encountered following Maxwell equation in cgs system ▽×H = (1/c)((∂D)/(∂t))+((4π)/c)j,
▽×E = -(1/c)((∂B)/(∂t)),
▽.D = 4πρ,
▽.B = 0,
now , c is the speed of light in vacuum ,
my question is that we have studied earlier equation without this factor 'c' and 4pi in third equation, so how we get above equation in cgs( centimeter, gram, second ) system.

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...
