The Aharanov-Bohm (A-B) effect is one of the most fascinating aspects of
electromagnetism. It is generally recognized as being a QED manifestation in
which the Magnetic Vector Potential "A" can influence the phase/trajectory
of moving charges even when the magnetic field ...

What is Zitterbewegung?

I show that the electrodynamics' spin tensor is needed for
interpreting of works by Loudon, Bishop, Nieminen, Heckenberg,
Rubinsztein-Dunlop, Simpson, Dholakia, Allen, Padgett, Parkin, Knoner,
Garces-Chavez, McGloin, Dultz, Schmitzer, O'Neil, and MacVicar.

I'm sure this is fairly basic, but I'm a mechanical engineer so bear
with me :p  I have been trying to read up on some properties and
Maxwell's equations but its been while since freshman year physics.
I have seen a few demonstrations on how to make a spinning plate

B and E are two fields that act on charge, with the former doing no
work. So isn't B just that part of E which does no work? i.e. that
part of E which is normal to the velocity, v, of a charge and so could
be defined as E x v? So every E will have a B that is dependent upon

I've been told [1] that you can't make a permanent magnet that has the
same shape magnetic field as a toroidal electromagnet.
More generally, I suppose, let's consider the field generated by a
current through a straight wire.  I know that this produces a field

In grade school, I came across a brief mention in a 5th grade textbook of an
igniter that was used in 1930s gas stoves in place of a pilot light. The
device consisted of a thin Platinum wire located in the burner area. When
natural gas, containing a high concentration of Hydrogen ...

6th August 1945 when Japan suffered first Atomic explosion
In the month of August in 1945 atomic explosions devastated Hiroshima
and Nagasaki, killing over 1,50,000 people.
The first atomic explosion was triggered on 6th August and second on

Greetings Everyone,
Assume I have a surface S that is a PEC (perfect electric conductor -
lossless) with a surface current J and surface charge p. J is of
course a vector field and p is a scalar field.

I used to work with L-band communication signals, and I remember that
I once had to calculate the effects of a carrier-wave jammer on the
receiver we were designing. For radio waves and interference, we
assumed a model for our antenna, a model for our expected signal, and
