How does the symmetric alter the fact that Maxwell's equations are derived using Faraday's induction effect that is not luminous (not emitting light)?
GENERAL EQUATIONS OF THE ELECTROMAGNETIC FIELD." (Maxwell, Part III).
"the total electromagnetic momentum of the circuit, or the number of lines of magnetic force which pass through it, the variations of which measure the total electromotive force in the circuit. This electromagnetic momentum is the same thing to which Professor Faraday has applied the name of the Electrotonic State. If the circuit be the boundary of the elementary area dydz." (Maxwell, Part III).
"Equations of Magnetic Force.
uα = dH/dy  dG/dz............................................2
uβ = dF/dz  dH/dx.............................................3
uλ = dG/dx  dF/dy.............................................4
Equations of Currents...
dλ/dy  dβ/dz = 4πp'........................................... .5
dα/dz  dλ/dx = 4πq'........................................... .6
dβ/dx  dα/dy = 4πr'........................................... .7
We may call these the Equations of Currents." (Maxwell, Part III).
