Maxwells equation in cgs system

Click For Summary

Discussion Overview

The discussion revolves around the formulation of Maxwell's equations in the cgs (centimeter, gram, second) system, specifically addressing the presence of factors such as 'c' (the speed of light) and '4π' in the equations. Participants are exploring the differences between these equations and those studied previously without these factors.

Discussion Character

  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant presents the Maxwell equations in the cgs system and questions the inclusion of the factors 'c' and '4π' in the equations compared to earlier studies.
  • Other participants provide links to external resources, such as Wikipedia pages, that may offer additional context or information regarding Gaussian units and the cgs system.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as it primarily consists of one participant's inquiry and others directing them to external resources without directly addressing the question posed.

Contextual Notes

Participants have not provided detailed explanations or derivations regarding the differences in the equations, and the discussion lacks resolution on the underlying reasons for the presence of the factors in the cgs formulation.

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.
