                           UNCHARGED ELECTRONS
              It is PRETTY OBVIOUS, from observation and
         experiment, that static electricity BEHAVES MUCH

Hi, I have a question and would appreciate any help:
The force on a moving electric charge is defined in terms of the
magnetic flux density B, thus B can be measured. B=mu_o(H+M). Is there
any way to physically measure H? If you remove the original B source,

We say that EM forces are caused by the exchange of particles, explaining
that an electron fires off a photon towards another electron when they are
close, causing the other electron to recoil away - the force of repulsion.
But how do we explain the force of attraction using the ...

How does define a unit cell structure of triangular lattice?
I want to use FDTD method for calculate band diagram of photonic
crystals. There is no problem for square lattice and its unit cell for
FDTD calculation is square. But triangular lattice has problems. It

The classical Beth experiment [R. A. Beth, Phys. Rev. 48 471 (1935);
Phys. Rev. 50, 115 (1936)] was made 70 years ago. A beam of circularly
polarized light exerts a torque on a doubly refracting half-wave plate
which changes the state of polarization of the light beam. The beam

Hello to everyone:
There was some discussion with DRL in an earlier SPR post regarding volume
integration in curved spacetime and what is and is not possible.  I have
brushed up on this a bit with some off-line advice from Igor K. as well.

I'm working in the field of Magnetics, I  would like to compute the
Magnetic Potential from an electromagnetic equation. The Potential is
in the integral form involving the Bessel's Function.
All I need is how this integral equation can be framed into a solvable

Hello to everyone:
My newest paper, "General Relativity, Maxwell's Electrodynamics, and the
Foundations of the Quantum Theory of Gravitation and Matter," just posted to
ArXiV.

I am working on dielectric-lined circular waveguides and I am searching
for a reference on the orthogonality of modes. The only thing that I
found is in the link below but I am looking for something with more
details.

Can a magnet change the direction of light (generally, photon or maybe
electromagnetic wave)? _if yes, how? _

Heya group,
Does charge have anything to do with time?
I've been trying to truly 'get' why opposite charges attract, and for the
life of my I can think of no mechanism that does that, except something

While studying Maxwell's equations describing electromagnetic waves
traveling in two dimensions, I find two different definitions of the TE
equations in literature.  Both appear widely used, but they seem
contradictory.
