that is the first true thing you have said... once you do come back.

I have problem with the Faraday
effect:http://www.teachspin.com/instruments...ay/index.shtml

"Although Michael Faraday discovered this effect in 1845, it wasn't
modeled
quantum mechanically until the 1960's. These theoretical calculations are
too sophisticated for the undergraduate student, but an excellent
simplified
QM model is carefully presented in David Van Baak's AJP paper. (D.A. Van
Baak, Resonant Faraday Rotation as a Probe of Atomic Dispersion, Am. J.
Phys.64 (6) June 1996)"

In Maxwell's model inside of the solenoid are rotating wortices and they
rotate the plane of polarization.

In Heaviside's model inside of the solenoid is a flux. Do you know
(understand) how the flux can rotate something?
S*

you don't understand that the faraday effect relies on a material to
do the rotation. the magnetic field itself does not cause the
rotation it only aligns the molecules such that the polarization of
the light is affected. you could just as well ask how can your hand
rotate something when you turn a polarization filter or piece of
feldspar with your fingers. if the material is not present the light
does not rotate, and there are no vortices.

In Maxwell's model: "In Maxwell's 1861 paper 'On Physical Lines of Force',
magnetic field strength H was directly equated with pure vorticity (spin),
whereas B was a weighted vorticity that was weighted for the density of the
vortex sea. Maxwell considered magnetic permeability ? to be a measure of
the density of the vortex sea. "

What is in Heaviside model?
