Re: Displacement Current Demonstration

Hello Benj...

I just finished Jefimenko's prior book on Causality.

It is less daunting, and very lucidly explains the fallacy of attributing H
to E and vice versa. I recommend it before the other book I suggested below.
My "simple" derivation is consistent with his full derivation using
retardation concepts.

BTW I tried to send you a diirect email with my WORD derivation appended. I
also sent a copy to John P. He got his, but yours "bounced." I used the
email address shown below.

If you feel up to it, look into "Electromagnetic Retardation and Theory
of Relativity" by Oleg Jefimenko.

On page 38, he states that "Electromagnetic induction is frequently
explained as a phenomenon in which a changing magnetic field produces an
electric field ("Faraday induction") and a changing electric field
produces a magnetic field ("Maxwell induction"). (emphasis mine. he is
talking about Displacement Current) A detailed examination of the causal
relations in time-dependent electric and magnetic fields shows, however,
that neither of the two fields can create the other."

It is available on Amazon at about $30.

Bill,
Thanks for the tip! I'll probably give it a go at the university
library first before plunking down the $30! However, yes, this is
exactly the trouble spot because the dogma is that in EM propagation
the two fields are supposed to create each other (as say the energy in
a mechanical oscillator goes back and forth between kinetic and the
spring). And all this seems to be very much related to the Maxwellian
dogma of the "one E field" which also appears to be incorrect. For
example, electrical forces produced by a changing magnetic field are
so so different in properties from an electrostatic E field that they
couldn't possibly be the "same thing".
