The baleful effect of the myth of changing E causing H, changing H causing E.

Electromagnetic theory started with steady fields, and than progressed to slowly changing fields, for instance in the case of Faraday discovering electromagnetic induction. We can think of Faraday's experiment involving moving a magnet through a coil, or sending changing current through the primary and detecting current in the secondary. Since I have nothing to say about magnets, I stay with the transformer case. http://www.electromagnetism.demon.co.uk/images/7877.jpg In this case Faraday did not in fact discover that changing magnetic field caused electricity. Throughout the experiment, TEM waves are involved, and there is never an isolated electric field or an isolated magnetic field. Always there is an electromagnetic TEM Wave. There was no interchange between magnetic energy and electric energy. My article on the transformer as a transmission line http://www.ivorcatt.co.uk/2631.htm "It simulates both the two-turn inductor and single-turn transformer" was rejected for publication by the London IEE/IET, but the very similar article on the inductor was published by Proc. IEEE. http://www.ivorcatt.co.uk/2631.htm . (A very rare example of my writing getting past journal referees.)


According to Heaviside, Maxwell proposed Displacement Current in order to get over a paradox over the magnetic field created near to a charging capacitor. He proposed that the changing electric field across a capacitor acted like real electric current in causing magnetic field. He, and everyone including Heaviside following him all the way up to today (because http://www.ivorcatt.org/icrwiworld78dec1.htm is ignored) failed to notice that the electric current entering the plate of a capacitor first has to spread out across the capacitor plate before desiring to traverse the capacitor. (It is disputed whether Maxwell invented Displacement Current for this purpose, but Heaviside says that he did; saying "The heaven-sent Maxwell"). This led to the spurious idea that changing E field in space causes magnetic field, leading to the false, "Rolling Wave" version of the TEM Wave pronounced by Einstein and Feynman and virtually everyone else including (partly) Heaviside. http://www.ivorcatt.org/icrwiworld78dec1.htm .

This false (rolling wave) view of the TEM Wave makes professors and text book writers unable to grasp the TEM step Wave, which is central to today’s (post 1965 digital electronics) Electromagnetic Theory. http://www.ivorcatt.co.uk/cattq.htm . Insights gained from high speed digital electronics have not been allowed to influence or modify Establishment Electromagnetic Theory. Today's reigning Electromagnetic Theory is not influenced by work in high speed digital electronics - that is, the step or pulse as opposed to the sine wave which ruled before 1965.

The failure to grasp the TEM Wave, that is Heaviside's "slab of energy current", means that professors and text book writers cannot grasp the obvious flaws in the overall theory which are shown up by the TEM step Wave. However, it took decades for me to see them, so I should not complain. Of course, I am entitled to complain about the comprehensive blocking/censorship of my work. None of the content of any of my six books now on the www has got into any university course or text book.

The photographs in my 1967 paper clearly show that two electric currents must travel in opposite directions down a conductor. I failed to notice this for 40 years. The problem is resolved by "Theory C"; http://www.ivorcatt.com/2_4.htm "Electric current plays no part in the passage of a TEM step in the dielectric between two conductors." http://www.ivorcatt.com/2608.htm . Electric charge and current are merely non-existent mathematical manipulations of the edge of a TEM Wave or "Energy Current". The mathematical manipulation of something which is physically real is not necessarily real.
