How can Electromagnetric wave be able to travel with speed of light for only
small as 1 watt of energy?

I considered absorption of a circularly polarized light beam without
an azimuthal phase structure in a dielectric in the frame of the
classical electrodynamics. I calculate transferring of angular
momentum and energy to the dielectric. My result differs from the

This is probably a stupid and easy question for those who are familiar
with the subject, but here goes anyway. Is the phase of the field
generated by the coil the same as the phase applied to the coil(and
the coils are connected serially). I am assuming that if they are

Hello can anybody help me out with this question?
When the H field is too high the H-B curve will go to saturation. In
saturation is the electromagnetic engergy converted into heat? or just
redistributed more into the air around the ferrite?

Please let me know a good book to study electromagnetics: I study for
hobby, without any teacher, it should be intermediate between the
Griffiths- Introduction to electrodynamics and the Jackson (which is
my final target); it should be also with clear mathematical

hi there- i must first preface that i am NOT very good with science or
math at all... in fact, i'm writing a philosophy paper but i need help
trying to find a source to verify a scientific claim i'm discussing.
ok, so i remember from highschool chemistry that chemical bonds have

In order to prove that apparent change in d(fi)/dt does not produce
emf in the circuit, we have to design a circuit in such a way that the
whole circuit or a part of it moves in the magnetic field without
change in the flux linking with it. However hard you may try, whatever

SCHOENFELD-EINSTEIN RELATIVISTIC FORCE:
F = (m + y^3 B/c m0 v)a
This is the relativistic mass-varying force.
PROOF:

    Pugh's Unified Field Theory, The Command Field Of The Earth
           (A common cause of gravitation and geomagnetism)
    Chapter one.

In the articles 10,13,14 and 15, it is sufficiently proved that
magnetic field is a  real physical entity. It is generated when
current is accelerating, retained when steady and absorbed when
decelerating.

I'd like to be able to calculate the electric field in a salt water
solution (electrolyte) at the interface next to a glass layer
(dielectric), sandwiched in a capacitor with intervening air layers.
The following diagram illustrates the situation, as well as my approach:

SCHOENFELD'S LAW OF GRAVITATION:
Fg = G (y^2 m0 Y^2 M0) / r^2
where
   G = gravitational constant

Lectori Salutem,
I am having many difficulties trying to calculate the magnetic field
that is inducted by a current running through a coin. The current
enters the coin at the edge and leaves the coin through the center via

Let us first ponder over force acting at a distance. Whenever there
exists such a force between two bodies, the force vector always lies
between them. The bodies, depending on their nature, either attract or
repel in the direction of the line joining them. Force between two

Please excuse me if this is the wrong group to pose my question.
I am hoping someone would be kind enough to help me estimate or measure
the magnetizing force that is being generated within a solenoid. The
solenoid is part of a capacitor discharge mangetizer I have built. The
