Re: More on Lorenz contraction

Well, I'm glad that Purcell was right as I am, so whats the big deal. When
I work out my results I use the power expansion of the lorenz contraction to
work out the magnitude of the force and it comes out just right. Lorenz
applies at all velocities not just huge ones it is responsible for the
magnetic force as a cosequence of electrostatic force (coloumb) as you say,
so why bring magnetism in to it and the complex maxwellian equations when
the simple ideas of Purcell work.

In fact his methods do show that all phenomina within electromagnetism are
included without maxwell.

The lorenz contraction predicts a force on a charged body near a current
carrying conducter when it is static relative to the wire. This is because
the negatively charged object outside the wire sees the electrons at a
higher charge density than the positive fixed charges and so will be
replelled. I think this has been verified experimentally.

The magnetic model does not.

So if there is a force the ampere model of cicular lines of magnic force
round a current carrying wire is false.

A test!

I must find a way of trying it myself, I suppose I need an etvos balance or
chemical balance an electrophorus, a gold covered pith ball, switched
current source and a draft proof enclosure.

Not too expensive I would think.

Don't just look it up, I like testing old experiments...However I'd like to
know that it has been done.

The other thing this model predicts is a force on a conducting loop inside a
solenoid carrying alternating current such that the loop tends to be drawn
to the centre.

I would have thought it would have been done, when I measured it there was.
It would be interested in knowing the results of others.

I was not taught science at school and my natural curiosity was stifled by
those who wanted me to be a house painter. Thats the class based society of
the hell of Britain.

My Uncle brain damaged, my aunt brain damaged, my mother brain damaged and
me driven mad and brain damaged. Thats the British undemocratic society of
paid labouring slaves.

The Soviet Union was better for men like me, at least that is my personal
experience. Western men are slaves to the God Money and the Boss. It is
hell in the Wonderful west as many immigrants from Eastern Europe are
finding, instead of wealth they find slavery and death.

The slaves of the West will never rebel, they are all detected and
lobotomised and used as sex slaves and workmen doing constantly repeated
tasks.

It hell, with lobotomised slave girls being offered for sex and lobotomised
men sweeping the road, its hell in the West, every one has had their frontal
lobe removed.

Show me one free man in the West, just one and one free girl, just one, can
you find me just these.

I like Blueberry pie from America and American Apples is America free, is
there a free man and women in america? Just one? Show me.

Give me my brown derby! In Russia we all ate Caviar and lettuce and baby
potatoes boiled just right with butter and advocar and pears, it was just
lovely in the USSR. Have you ever had Russian scented chocolate with conuaq
centres? Or had fresh Sturgeon (like salmon) jusy pulled from the Dneiper
cooked over a pine tree fire eaten with roasted fir cones and berries from
the trees? I have.

And you could even sack you boss, and choose your project, it was so much
better in Russia.

You need to look, I think it is the page "new electricity".
It looks similar to:
http://physics.weber.edu/schroeder/mrr/MRRtalk.html

It has been fairly well torn apart in thin ng.


Here I reproduce the mathematics I learned in my degree course on
relativity, we did the special theory where I scored a 2,1 (I mixed up
over
line of sight and transverse movement and some of this stuff, like two
beams
of electrons - the force between them, do they exhibit any magnetic
effect?
I got wrong, got it right now) I only scored a 2,1 on my quantum
mechanics
course because I did not understand the hesenburg model, but I'm getting
there. My proff was professor Stannard. I got invited to go to the
states
to study Fineman, but politics got in the way.

I got 2,1 overall.

I did some more experiments with a compass needle in a loop of wire

a current as well as repeating the solenoid experiment, this morning.

For a single turn the deflection was 20 degrees at the axis and 30

wire (approx), for the solenoid the deflection was the same at the
axis
as
near the wire.



The results obtained with the single turn together with the results of
the
solenoid I come to the conclusion that a single turn gives a different
result from a solenoid.



This indicates that magnetism is not the phenomena that philosophers
thought
is was for 300 years since Gauss.

Lorentz contraction has nothing to do with it.

Look again.
Count the t's on this page:

gauge independent: i.e., they do not depend on the particular

I have done vector field theory but I find the notation, altough precise,
contains a lot of equations that need writing out in order to understand
what is involved.

In other words I found the notation too abstract, this is because I had a
non malignant growth removed from the language region of my brain and had
to
re-learn talking and the notation of mathematics. If I remember rightly
I
made a contribution to the notation of vector field theory. When I did
electromagnetism we used non-vector calculus, and wrote it all out in
cartesian form, even maxwell's equations.

Yes I gave you the URL for the time-independent version.


As far as I understand it, using the length contraction model, it can be
regarded as an alternative representation.

No... it is faulty, No matter is moving a significant
fraction of the speed of light to permit the application.

Use Multiple integral for spatial version.
Use retarded potential for temporal version.


However by noting that the force
between current carrying conductors may be calculated exactly in
electrostatic term of charge densities seen as a result of the lorenz
contraction does mean that the concept of magnetism is not valid.
Magnetism
is in reality an electrostatic effect. This simplifies the model rather
than making it complex.


Deleting the concept of manetism is an application of occums razor.
Yes... Maxwell and Weber did it over a century ago.

It is just a derivative of the Coulomb force. You can use the
multiple integral and Biot Savart or Ewald summation to prove it.
Nature uses neither method so occam's razor doesn't
count in mathematics.

You shouldn't use the time dependent version for notational
simplicity because it hides the superposition and forever
saddles you with these restrictions:
http://arxiv.org/abs/physics/0204034

If you have a particle accelerator then you can actually
observe Smith-Pucell radiation and the time-dependent
equations are appropriate to describe how the beam
interacts.

For low velocity charges in a wire, a spatial integration
better describes magnetic force.

Sue...


Before my late teens I had these ideas but I was assualted by a
psychiatist
hired by mum "to make me successful". Mum would say "why does he not
work
for money" when doing these experiments and mathematics. His brain
operation turned me into an idiot incapable of any work of any kind, I
could
not even drive a push lawn mower.

By 19 I had recovered the use of my frontal lobe and began this sort of
stuff again, I got married and started to be succesful, he then framed me
for something he did in order to destroy me. He succeeded.

The men concerned have hunted me for 30 years, unaware to me, but they
missed me because another man concerned, who returned from a carreer in
Africa to assualt me (legally), he is a magistrate with highly eccentric
and
exreme religious convictions, lived just in the next road and now has
found
me and recently assaulted me again after I published another book, but
his
assault destroyed most of my memory, I'm told the concepts are still
there.
He is mad, he mapped the nervous system, I saw his book, and because he
does
not understand a bit he thinks it does not do anything and casually chops
it
out.

The name of the man: Well write to me privately and I will tell you.

These assaults have to with my religious convictions and the whole
christian
church seem to be involnved, several of my friends have been murdered, or
threatened with death, its getting like Kosova here.

These ideas are nothing to do with it.






Sue...

Nice to meet you sue!
