comment Are the Maxwell's equations enough to derive the law of Coulomb?
@Daniel Blay: I guess when you say usual tricks you mean taking a spherical surface around the point charge. The problem for me is that how do we know that the magnitude of the electric field from a point charge is spherically-symmetric. Besides how can we derive that there is no magnetic field (if it is possible to derive from Maxwell's equations)? :)

comment Are the Maxwell's equations enough to derive the law of Coulomb?
@DanilH: I meant 8 scalar equations. From the 4 Maxwell's equations two are vector equations.

Yes, I have already read this post, but my question is quite different.

@Qmechanic : Could you please give the explanation of the Hamiltonian action. Why does it depend on momentum path?
