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 :-) � > 2) Magnetic field is produced only when the electric field of the wave > move > electrons 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 :-)))) Italian examples in : http://www.asps.it/pastore2011.htm http://www.asps.it/mito.htm � > 3) Electric waves move themselves in a medium which compensate the non > 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 :-) � > E.Laureti Good Luck! � quo fata ferunt E.Laureti �
