Electromagnetic
Induction
Faraday closed the switch between battery and primary
in his transformer. See diagram http://www.ivorcatt.co.uk/7877.jpg
. A Transverse Electromagnetic Wave
proceeded towards the primary. It contained magnetic as well as electric field
(actually a single electromagnetic field). When it reached the front face of
the secondary, some of this field leaked out into the secondary as indicated in
the second trace of Figure 36 .
The front end of the secondary being shorted, no voltage was apparent there
(although there was energy), but it developed later, further down the secondary
as shown in the second trace. Again looking at the diagram http://www.ivorcatt.co.uk/7877.jpg
, on reaching the end of the secondary,
some of the energy travelling in the secondary continued towards the
galvanometer. This energy was also in the form of a TEM Wave, and contained
magnetic as well as electric field. However, the galvanometer only measured
voltage.
At every stage in this process, a TEM Wave was
involved, There was no transfer between electric and
magnetic fields. Electric current was not involved.
The energy builds up in the primary of the transformer
in a manner similar to the way a capacitor is charged, as in the Figure 3 in my
article "Displacement
Current" .
Find “REFLECT TWO SHORTS” in "Forrest
Bishop" for illustration. Also see Mike Gibson's illustrations .
The second article; "The Inductor as a Transmission
Line" is also relevant.

are needed in the contemporary body scientific.
1) We

2) We

Since 1910, when science
became too prestigious, the Establishment has outlawed the idea of “mistake”.

Dear
Ionel,
I
have written this for you.

Faraday
did not discover electromagnetic induction. He discovered crosstalk. http://www.ivorcatt.co.uk/x147.pdf
. My article mainly deals with crosstalk to a second pair of conductors open
circuit at the front end. However, Figure 36 shows what happens as in a
transformer, when the pair of wires in the
secondary are shorted together at the front end. Still, some of the TEM Wave
leaks out into the secondary.
The
key point is that it is impossible for a TEM Wave to travel along down a pair
of parallel conductors (e.g. transformer primary) and leave a second pair of parallel conductors (e.g. transformer secondary) unaffected. The conventional
maths at the end of the article proves this, using classical theory
