Derivation of Maxwell's equations from field tensor lagrangian
I know I should end up with $\partial_\mu F^ {\mu\nu} = 0$, but I don't quite see why. Since $\mu$ and $\nu$ are dummy indices, I should be able to change them: how do the indices in the lagrangian …

electromagnetism - How to derive source-free Maxwell's equations …
Phrased differently, since the source-free Maxwell equations are manifestly implemented from the very beginning in this approach, varying the Maxwell action S[A] S [A] will not affect the status of the …
electromagnetism - What are the differences between the differential ...
May 19, 2016 · The differential forms are far easier to manipulate when dealing with electromagnetic waves; they make it far easier to show that Maxwell's equations can be written in a covariant form, …
Can the Lorentz force expression be derived from Maxwell's equations?
From Maxwell's equations we can get the induced charges in the plates, and also the induced currents. If we know the electrostatic force due to the charges, then the two plates must be attracted to each …
How is the speed of light derived in Maxwell's equations?
Oct 5, 2019 · The speed of light, denoted as c, is derived from Maxwell's equations as c = 1/√ (μ₀ε₀), where μ₀ is the permeability and ε₀ is the permittivity of vacuum. This derivation shows that the speed …
Is the Constancy of Light in Vacuum a Proof or a Postulate?
Jun 24, 2012 · The other postulate was of course the relativity postulate which implied that the true laws of electromagnetism would have to be the same in all inertial frames. In the paper, he did not …
Independent equations of maxwell equations • Physics Forums
Aug 23, 2011 · Maxwell equations are 8. we need them to determine electric and magnetic field. the component of magnetic and electric field are 6. in linear algebra say for solving a system of equation …
What does a Galilean transformation of Maxwell's equations look like?
Jan 9, 2018 · But my question is, what are the equations that people thought were true in frames other than the aether frame? To put it another way, what are the equations you obtain if you apply a …
electromagnetism - Do Maxwell's Equations overdetermine the electric ...
Jan 31, 2015 · The Maxwell's equations do not over-determine the electric and magnetic fields. This becomes clearer if we rewrite the four Maxwell's equations into one using geometric algebra:
