Hi:

Dielectric strength and ohm [electric resistance] are electric entities.
What are their magnetic equivalents?

Are there such things as "dimagnetic strength" and "magnetic
resistance"? If so, what are they measured in?

Also, is there such a thing as "magnetic conductance" [like electric
conductance]? If so, what is it measured in?


Thanks in advance,

Radium

"Magnetic conductance" got over 100 hits. Can you imagine your other topics
may also have something waiting for you at Google?

Electric conductance is measured in "siemens". WTF is there no SI unit
for "magnetic conductance"?

http://dictionary.reference.com/browse/magnetic%20conductance

http://www.reference.com/search?q=magnetic%20conductance&r=d&db=web

"There are no dictionary entries for magnetic conductance, but magnetic,
conductance are spelled correctly."

WTF is that all about?

Similar with "magnetic resistance". I searched but couldn't find any SI
units!

Quote from http://en.wikipedia.org/wiki/Magnetic_effective_resistance

"Magnetic effective resistance is the parameter of a passive magnetic
circuit or its element, which is equal to the relation of the effective
power, which is absorbing in this element, to the square of the
effective value of a magnetic current in it."

Magnetic current???? You mean to tell me such a paradisical and magical
entity exists????

Magnetic current requires the existance of magnetic monopoles -- which,
unfortunately, do not exist. I wish they did, that would make life so
much more interesting.

Nothing on "dimagnetic strength"!

Quotes from
http://www.google.com/search?hl=en&lr=&q=%22dimagnetic+strength%22&btnG=Search

"Did you mean: "diamagnetic strength"

"No standard web pages containing all your search terms were found."

"Your search - "dimagnetic strength" - did not match any documents. "

It's obvious that "diamagnetic strength" means something totally
different and unrelated to my analogy. Diamagnetism is the ability of
normally non-magnetic substances to "feel" a repelling magnetic force --
this allowed for the experiment of levitating a frog. However, this is
totally irrelevant to what I am discussing!!!!!!!!!!!

"Dimagnetic" and "diAmagnetic" are two totally totally different
things!!!!!!!!!!!!!!!!!!!!!!!!!

What is the SI unit of "dimagnetic
strength"?????????????????????????????????????????????????!!!!!!!!!!!!!!!!!!!!!!!!!!!?!?!?!?!?!?!?!?!?!?!?!
Not "diAAAAAAAAAAAAAAAAAAAAmagnetic
strength"!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


I am looking for a material with *all* the following characteristics:

1. Infinite electric resistance

2. Infinite dielectric strength

3. Zero magnetic resistance

4. Zero dimagnetic strength


If such is not possible, then
why????????!!!!!!!!!!!!!!!!!!!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?! Why isn't
such
possible????????????????????????!!!!!!!!!!!!!!!!!!!!!!!!?!?!?!?!?!?!?!?!?!?!?!

Huh?

I want to seperate magnetism and electricity as much as possible.

A telephone wire should consist of a magnetic conductor that will carry
magnetic non-electric signals to convey data.

This wire should consist of a material with *all* the following
characteristics:

1. Infinite electric resistance

2. Infinite dielectric strength

3. Zero magnetic resistance

4. Zero dimagnetic strength

This will allow efficient telecommunication with only one disadvantage:
bad carrier-to-interference ratio.

"Magnetic current" is what can make allows a permanent magnet to cause a
normally non-magnetic piece of iron [such as a steel paperclip] to
become magnetic.

Place a permanent magnet close to the iron paperclip for a long enough
time. The paperclip will become a temporary magnet.

Data can be transmitted/recieved across across long iron wires [assuming
the wires are long enough for telecommunication] using a similar technique.

Unfortunately for me, iron conducts electricity so it does not fit my
above 4 requirements.

No separation is possible. Magnetism is charge and motion. Take
away either one, and you have no magnetism.

I want to understand the limiting factors of the speed of light so we might
exceed, in some manner, what now is considered immutable law.

I want to understand all aspects of gravity, to enable me to create an anti
gravity device that can lift heavy weight at relatively low energy input.

The way you're going at it, I will certainly reach my goals before you reach
yours.

If something appears impossible, it is only so because we lack knowledge.
The universe is open for us, through study, to find everything we seek,
though we may not appreciate the answers.

Asking everyone else for answers to your questions is a waste of everyone's
time, including yours. Study, learn.

Come on Don! Now Radium (Green Xenon) asked this question in a very
nice way and nobody has really responded with the kind of answers he
needs! If you people don't start answering his questions you are all
going to be VERY SORRY!!!

If Radium has a question you are all duty-bound to serve his every
spamming wish! If not you'll probably be persecuted by MI5! I know I
have been. The other day I approached a bus stop on Broad street and
there were several persons standing around there. I asked them the
time and they replied "four o'clock"!!!!!! I KNEW that they were
mocking me and they were MI5!!!! And as I turned and left I could hear
them talking among themselves. I knew they were agents on the
attack!

Yes, and they were all there hoping to jump in front of a speeding to escape

Look up magnetic circuits, http://en.wikipedia.org/wiki/Magnetic_circuit

However, the concept of magnetic resistance or its inverse conductance is
easy for visualisation but is not generally of much use in practice because
either the "circuit" is rather diffuse or the elements are non-linear so
the resistance concept becomes rather useless (Ohm's Law is invalid in such
a situation which is a point that is not made clear in Wikipedia). Magnetic
vs electric circuit concepts are good approximations where definite flux
paths are definable as in transformers, relays, motors etc where non-linear
effects are negligable.

Might I suggest that you do get some good texts dealing with the topic of
magnetic devices and circuits. Mind you, many start at the Maxwell's
equation level and simplify down to some practical devices on the basis of
reasonable approximations.

Hi Radium,

Electric Current density =

spec. conductance * El. Field strength

Magnetic flux density (vs/m2) =

permeability (vs/Am) * magnetic field strength (A/m)


Electric current = conductance * voltage

Magnetic flux (Vs) = magnetic conductance * magn. Field strength (A/
m).

Magnetic resistance = 1 / magnetic conductance.

Magnetic resistance = length / (Area*permeability)

Length is length of magnetic path, Area is cross section of core
material.

For core inductors: L = turns2 / magnetic resistance

Magnetic self inductance goes in Vs/A.

Hope this helps a bit.

dimagnetic strength??? Since you apparently have something in mind other
than "diamagnetic.." and nobody knows what you mean by this term, it is not
possible to express units for it.
Do you have some sort of definition as to what you mean by this term? Do you
mean permeability or its inverse?
Again, you are trying to come up with some EM proposals without attempting
to learn the basics of EM theory. Until you show some more knowledge of what
you are talking about, no one is going to take you seriously- some will be
polite and others won't and continuing as you are doing will turn off the
polite ones.

Dielectric strength = the maximum electric field strength that a
material can withstand intrinsically without breaking down

Dimagnetic strength = the maximum magnetic field strength that a
material can withstand intrinsically without breaking down

Dielectric breakdown causes an insulator to lose its insulating properties.

What would dimagnetic breakdown cause?

Hello,

In ferromagnetic materials, above a certain magnetic field strength
(inside the material), or flux density, the contribution of the
material to the flux does not increase with increasing H-field. The
material is fully magnetically polarized (saturation).

What about very strong magnetic fields? I know from certain magnetic
materials that very strong magnetic fields cause permanent changes to
the magnetic properties of soft ferrites. I do not know the physical
explanation for that.

No, the term "magnetic current" is not being applied to magnetic
monopoles in those references. It is referring to electric charges
moving in a circular pattern or some approximation of it. The term
"electric current" is being applied to electric charges moving in a
straight line pattern or some approximation of it.
Note that even in this definition, a "magnetic field" is not a
"magnetic current." The analogy of some objects with nonzero rest mass
moving from the south pole to the north pole is still not valid.
I know that I said earlier that magnetic current refers to the
motion of monopoles and I am sorry. I apologize. However, the way your
question was asked logically implies the existence of isolated
magnetic monopoles. The magnetic field is not a magnetic current.
Nor at present has anyone isolated a magnetic monopole. The
mathematics implies that a small loop of circulating electric current
can be replaced by an equivalent magnetic dipole, which can be
pictured in approximation as two magnetic monopoles of opposite
polarity very close together. However, this is an APPROXIMATION. The
two monopoles do not really exist. If one were to try and separate
these make believe magnetic monopoles, one could get a shock from
electric charge. The flow of these make believe "magnetic monopoles"
would be a magnetic current. Somehow, these engineers have decided to
place this APPROXIMATION in the definition.
Sheesh, engineers. Placing an approximation in a definition. I am
so glad I am a physicist. I would never refer to a circulating
electric current as a magnetic current. I promise you that in my
physics classes I will warn the students the coming approximations
before I use the words "magnetic current."


I didn't know this before you asked the question, so thanks. I
did look further at the same Wikepedia references.
I got this by searching for the term "magnetic current" in the
"Magnetic Field" entry on Wikepedia
(1) Magnetic induction current causes a magnetic current density

\mathbf{B} = \mu \mathbf{H}

was essentially a rotational analogy to the linear electric current
relationship,

(2) Electric convection current

\mathbf{J} = \rho \mathbf{v}

where ρ is electric charge density. \mathbf{B} was seen as a kind of
magnetic current of vortices aligned in their axial planes, with
\mathbf{H} being the circumferential velocity of the vortices. With Âľ
representing vortex density, we can now see how the product of Âľ with
vorticity \mathbf{H} leads to the term magnetic flux density which we
denote as \mathbf{B}.

The electric current equation can be viewed as a convective current of
electric charge that involves linear motion. By analogy, the magnetic
equation is an inductive current involving spin. There is no linear
motion in the inductive current along the direction of the \mathbf{B}
vector. The magnetic inductive current represents lines of force. In
particular, it represents lines of inverse square law force.
