So far as is known at present nobody has shown the actual existence of
a displacement current (and its so-called magnetic field). Several
experiments purporting to do so have been shown to actually be due to
the flow of current in the plates of the capacitors. The question is
still open.

� yes but i hope only that  needn't 150 years more :-) �

Hence the "major" proof used in this regard (and the reason the
displacement current term was added to Maxwell's equations) is the
existence of EM waves which mathematically require displacement
currents for their existence.

� it is the word "matematically" for which i am not convinced . Physics 
directs mathematis when we speak of physics and not the contrary �

But the whole scheme is based upon an error. That error is that
changing electric and magnetic fields can "create each other".

� i agree completely  it is a methaphysical opinion of mr. Maxwell that 
destroy the physical perception about e.m. waves for more than a a 
century...an error that was accepted 150 years more without experimental 
verification and that it a scandal for the orthodoxy science to mantain �

A
careful examination of Maxwell's equations with regard to causality,
shows that this CANNOT be true. (See Jefimenko's books) The truth must
be that both Electric and Magnetic fields are generated ONLY by
currents and then propagate together through space!  Hence charges and
currents are the ONLY source for these fields.

� i agree completely �

>  From my experiments I can find only such conclusions:

> 1) E.m. waves are only electric waves

This is not correct. EM waves do indeed consist of both electric and
magnetic fields. Magnetic fields exist. But E and B fields do not
"cause each other"

� i never find such magnetic part of waves but suddenly i change opinion 
when it happen.
For example every type of loop between the plates of a capacitor or for a 
wave interception in free space never show 180 degree phase angle when it is 
turned off of 180 degree
(180 degree changement happen when a loop feels the magnetic field produced 
from moving charges).
For example in http://www.asps.it/vol30.htm (our very little issue Nova 
Astronautica) at Vol.30 n.125 i show an ambigous attempt to find such field 
(fig.B and Fig.C) . You can see no phase between the two traces in the 
oscilloscope for different position of the loop . The author of such 
experiment
 http://www.physics.umd.edu/lecdem/services/demos/demosk2/k2-63.htm probably 
had some doubt so he say at the end "to perhaps demonstrate displacement 
current" becouse alleged two magnetic field traces don't show any phase 
angle :-)

Absolutely correct as I noted above. When E and B fields are expressed
in causal form, each is ONLY produced from charges and currents. They
do not "cause each other".

� i completely agree but say to me in what manner we can communicate this 
orror to 99.9 %  of believers in Maxwell methaphysical physics : most part 
will accuse you don't understand
Maxwell equations and morever that you say e.m. waves don't exist becouse is 
Maxwell theory that prove the existence of e.m. fields  :-))))

> existence of magnetic field

Well, there are a lot of open questions here. One being what exactly
IS a magnetic field? And HOW is it created from charges. Same goes for
Electric fields. Some say a magnetic field is simply a "flow" of
aether. In that idea the "field" is really just a property of the
medium.

� i really have ideas but before i think that it is necessary remove the 
iceberg of errors of Maxwell theory  away from physics �

Of course, "modern" physics denies that waves require any medium at
all to propagate. The idea is that "waves" are simply equations and
that mathematics is more real than reality.
 In other words EM waves
are some kind of "magic". As you will see, there are many who will
strongly argue this nonsense point of view which explains how errors
have persisted for so many years.

� a big fighter against "the ....... arrogance of mathematical physicists 
giving priority to formalism against empirical facts....." is our asps 
member prof. U.Bartocci www.asps.it/gotha.htm     �

Which is why I believe when things have been around for a long time
(Maxwell's equations for example) that means it's a good time to go
back and go over the whole business again in detail in the light of
advances and discoveries since those days.

� a miracle probably will release physics from Maxwell comical errors :-) �
