Delayed Lenz or not?... post your explaination!

[MileHigh]

You are on the wrong track Tinman.  The speed of light or magnetic field propagation speed does not affect the operation of a transformer or pulse motor at the frequencies we are normally dealing with.  It's just a few picoseconds for the magnetic field propagation.

Here is a fun factoid:

The speed of light is 300 million meters per second.  Therefore light crosses one meter in about 1/300,000,000th of a second, which is 3ns -- or roughly 1ns per foot. 

A modern quad-core CPU running at 3GHz, assuming each core is swallowing two instructions per cycle, processes 8 instructions every 0.33ns.

It is processing a couple of dozen instructions in the time it takes the light to get from your monitor to your eye. 

Is it just me, or is that kind of cool? 

(it also hints that it wont be long before engineers are running up against the speed of light in all sorts of places)

The relative permeability is just a coefficient.  It does not change the physics.

Round and round we go.  The very effects that are used to claim "delayed Lenz" effect are in fact the result of Faraday induction acting immediately and in the orientation predicted by Lenz' law.

@MarkE,

Everything you guys say is just vapid meaningless bullcrap.
