UNLOCKING THE MYSTERIES BEHIND RADIO WAVES.
Electric current creates magnetic field, oscillating electric
current creates oscillating magnetic field and not
"electromagnetic wave" as current belief. Electron has a standing-
electric field and magnetic field at right angle (watch video
structure of electron). The flow of electrons in a conductor is
essentially caused by the attraction between the electric fields
of mobile electrons and "fixed" positive charges in the conductor.
Oscillation of electrons in a conductor is caused by the
alternation of electric polarity in the conductor. Because of
electric field and magnetic field of an electron is at right
angle, when oscillates the electric field of the electron will be
parallel to the oscillation and magnetic field will be
perpendicular to the oscillation.This oscillation of the electron
creates transverse wave on its magnetic line and the oscillating
magnetic line is radiated to space.

Hello,

I've been searching for an answer to this question for years. I'm
hoping somebody here can answer it or at least point me in the
direction. Or maybe I'm totally off base on my basic understanding and
so this question is out in left field.

I've been to howstuffworks.com and read a few articles on radio; I
learned a few cool things, but not what I was after.

Here's my question. When a radio tower, or whatever, sends out a wave
it has to propagate somehow. I figure this works by making electrons
do their thing, vibrate or whatever those crazy nothings do. If a
group of electrons is creating a field or sending a wave it has to be
at a specific frequency, but what I don't understand is how can there
be the plethora of frequencies all at the same time in the same place?
Can't an electron only vibrate at one frequency at a time? In simple
terms: how can my radio have the potential to tune into all the
stations; how do the waves not interfere with each other?

In wave theory, in physics class, I remember sending one water wave
from one end, and another from another end, and they cancelled each
other out. Wouldn't a radio wave work the same way?

So many questions, so little time...

Thanks,
Bodi
