Natural Science Forum / Physics / Electromagnetism / April 2005

I don't speak fluently English but I want to learn and understand
eletromagnetics.
Do you now a french newsgroup about electromagnetics or physics ?

I made a half-dipole antenna for my home stereo from wire scraps I had.  It
works fine, but unfortunately, my two favorite radio stations are
geographically 90 degrees apart (East, and South).  With the dipole being a
directional antenna, that, of course, means sacrificing one ...

Various theories have been put forward in the last century or so
attempting to explain the phenomenon of intertial mass in terms of the
electromagnetic interactions of the charged particles of which that
mass consists.

I hope this is the right group in which to post this question, but
please advise if it may not be.
I was curious as to whether or not a certain effect should be
possible... I refer to this kind of set-up:

Is there a table of the speed of electromagnetism in different materials,
such as copper.  I can only find the speed of light in glass, diamond,
galliumPhosphide eg transparent materials with a refractive index.

I wanted to neutrinolize the Maxwell Equations in the 1990s. I wanted to
do this because I felt DeBroglie was correct on his intuition that the
neutrino and photon flip flop into one another. I was reinforced with
the idea that gravity was a real force distinct from Coulomb force ...

I am using Quickfield to model the effects of two coils, one larger
than the other, on each other.  The first coil is set with a current
density of 100,000 A/m^2 through it while the coil on the right has 0
current density and u=1.  The problem was set up in magnetostatics.

Maxwell's first equation can be written as well in differential as
in integral form. A special variant of the integral form is its
parallel-planes version:
 The difference between the integrals of the electric flux through

I know these are dumb questions...but I believe the most mysterious
also(atleast to me)!!!
How is propagation of electromagnetic waves affected by change in
dielectric constant of the atmosphere?

I know (don't ask me how:) ) that following questions are stupid, but I need
to know :)
1. I can't get a grip on how electric field is produced in a relativly long
wire, for instance connected on a 1.5 V battery, about 5 meters long. How

I was standing  holding an umbrella on the train station platform in
Cambridge.  I gently touched the top of my head with one of the metal
spokes in the umbrella and received a slightly painful shock,
accompanied by a fizzing humming sound.  There were overhead power

imagine a point at 1000 V: what is the behaviour of the electric field
around it? Does it change if you change the middle material (for
example, plastic in place of air and then iron in place of plastic)?
Thanks

I have not received this book yet and it may take a month before I get
it in my hands.
But what I expect to find is that Landau and Lifschitz never derived the
Maxwell theory from starting principles of Least Action or Least Time.
