I understand that coaxial cable does not radiate much energy because
symmetric opposing current sheets in the outer skin of the center
conductor and the inner skin of the shield essentially balance each
other.

Tech-X Corporation develops and sells a software product -- OOPIC Pro
-- for simulating systems and devices involving electromagnetic fields,
charged particle beams and or plasmas.
In an effort to better understand the simulation needs of the relevant

Not quite sure if this is the best place to post this but it's a start
I guess.
3 months ago I moved in to a new house, I live in Scotland,
incidentally, the house itself is only 2 years old. About 80 metres

Isn't it that changing electric field can cause magnetic
field. This is why alternating current has magnetic
field. But the physics wiz said direct current can
also produce magnetic field. But isn't it that the

This is only for those new generation of Quantum Vacuum
hidden riches researchers and unified relativistic
Aether theoreticists.
When magnetic field are cancelled in opposing current

What shape would the magnetic field of a horseshoe magnet take as the
poles are pushed together?

In regions where the magnetic field is zero. The
magnetic vector potential can still affect the phase
shift of the electron.
Does this mean that in a special coil where the magnetic

Suppose you have 220 volts AC and a load such as an
electric fan. Is the current before and after the
load exactly 100% similar in value? Are there loads
wherein the current can become different before and

Is it necessary that only metallic conductors can radiate
electromagnetic waves? Can a non-metallic conductor or insulator,
radiate electromagnetic waves? I'm asking this because all the
antennas I've seen are made of metallic conductors, and I recently

Say we have a simple DC circuit, where a battery from it's +ve terminal
to a resistor with a wire (let's call it the +ve wire), and the other
end of the resistor is connected by a wire (let's call it the -ve wire)
to the -v terminal of the battery.

I have uploaded a diagram of a simple circuit here
(http://www.geocities.com/likkle_gaya/ElectricFieldSimpleCircuit.JPG).
The diagram has emphasis placed on the valence and conduction band
electrons of the copper wires. I know that there exists a voltage

I am building a circuit with minimal magnetic field so as
not to disturb nearby circuits. Can anyone enumerate the
coil configurations that can cancel two opposing magnetic
field to produce zero magnetic field. Is it called mobius

So I need to add a basic term into the Maxwell Equations because the
force of gravity is a fiction force. Gravity is replaced with a Cosmic
Coulomb force where the Nucleus of the Atom Totality of 231Pu has 94
Protons that attract its 94 Electrons of which the 5f6 of its last 6

Every so often a daughter, spouse, or relative would ask, "When
you die, do you want to be cremated or buried?"
At first I'd say "I don't care."  Or "I'll be dead, it won't
matter to me." Or else I'd start a rant about death-phobic
