message: Nigel, if the velocity of propagation of a transmission line were independent of the construction of the line, manufacturers of coaxial cable would not need to supply the inormation on their datasheets. You are confusing the speed with which the change in the magnetic field spreads when you slide a fridge magnet around your fridge door with the speed that the fridge magnet itself is moving. -- Kevin Brunt 12:32, 1 June 2006 (UTC)
replies: text: Kevin, we're talking about conductors with vacuum as the insulator; coaxial has a speed equal to light speed for the dielectric (the dielectric contains plastic insulator with a molecular dielectric that becomes polarised in an electric field).  For vacuum, the velocity in a transmission line is always 300,000 km/s, and changing the construction of the line only alters the characteristic impedance and resistance.  Make the conductors thicker and you can decrease the resistance (ohms per m of length) and impedance (ohms).  Look at the diagram on the page: radiation is emitted perpendicular to the direction electrons are accelerated to cause a drift current.  So you are confused!  Before you go on that the electrons are already moving, the electrons inside me are already moving before I begin to walk but I still have to accelerate them to move (the net velocity before is zero, and after the wavefront passes the net drift velocity is 1 mm/s or so for 1 amp, which implies an acceleration).

message: :Kevin, Prof Calvert's argument as you summarise it would allow the Catt Anomaly to be simplified by reducing the wire diameters until you remove the wires altogether and just have two parallel beams of electrons (like beta particles) being fired in space in opposite directions.  The absurdity of this model is at once apparent: it can't simulate the TEM wave.  Two beams of electrons representing current flows in conductors would limit the speed to that of the electrons, which is less than light.  As said before, the TEM wave is not caused by electron drift.  The light speed TEM wave in current physics is an effect of light-speed, force-causing Yang-Mills radiation, because that is what the electromagnetic field is composed of in the highly successful Standard Model.  Electrons move in response to this field.  When the electrons move they radiate energy at right angles to the direction they accelerate, and this radiated energy gets exchanged between conductors.

replies: text: Kevin, I stated in the paragraph above your entry that it is "absurd" that electron beams are equivalent to electricity because electricity goes at light speed while the electron beams move more slowly.  You then "respond" by stating that there is nothing absurd.  Perhaps you need to read the paragraph again more carefully so you can see the reason why I am saying the analogy is absurd: velocity.  For the mechanism involving electron drift (electric current), see my analysis of the Catt Anomaly here: http://electrogravity.blogspot.com/2006/04/maxwells-displacement-and-einsteins.html  Nigel 172.143.1.219 19:45, 29 August 2006 (UTC)

text: Kevin, by "electricity" I mean what powers things when you close a switch.  The problem is not in my definition of electricity, but in the idea of 1 mm/s electron drift current somehow delivering significant energy, when we already know the truth: quantum field theory tells us that the electric field is mediated by light speed radiation (gauge bosons of electromagnetism).  Why try to explain c-speed electricity using 1 mm/s electron drift when the mainstream theory of the field is already c-speed gauge bosons?  Why try to use a 19th century theory which is false, when you have a better 20th century theory handy?  That is absurd! Nigel 172.188.235.104 21:41, 30 August 2006 (UTC)

text: Kevin, the point is that electric current is the result of electromagnetic fields.  If you send logic signals of same amplitude in opposite directions along the same transmission line, there is no electric current while they overlap, there is just energy current for the duration of the overlap.  Dr Walton did the research on this and proved it theoretically as well as by experiment.  It is vital.  See page http://www.ivorcatt.com/1_3.htm top illustrations: while two opposite-travelling logic pulses overlap, if they have similar amplitude they cancel each other's magnetic fields (because the B-fields have opposite curls), and during overlap there is no variation in voltage along the line, so the field E = dV/dx = 0/dx = 0.  Hence there is no electric [electron drift] current, there is only Heaviside-Poynting energy currents going in both directions creating a detectable net voltage (although no gradient in that voltage along the overlap region since dV/dx = 0), and nothing else.  You are the one who leaves out the forces acting on the electrons; I keep telling you that the Standard Model says those forces are gauge bosons which constitute the field, and they go at light velocity.
