Magnet Myths and Misconceptions

An endless circle NoBull.
But feel free to tell us all how this material gets into space from earth to be cooled without the use of energy?.
Sounds to me as though this cooling process is getting quite expensive

If the material emits between 1u and 8u there is nothing in its way.

If we use the wire with a current flowing through it that produces a magnetic field around that conductive wire as an example-dose anyone know of a conductor that dose not produce a magnetic field around it when a current is passed through it?.

It is the current that makes for the field.  The wire is mereley a means to carry the current.  You get the same effect projecting an electron beam.

Tinman:

What is the basis for you posing that question?  Any wire that has current flowing through it will have a magnetic field around it.  In fact there is even a magnetic field inside the wire.  That leads into a related question.  What is the simplest inductor?  The answer is a short length of straight wire.

It makes me think of when people post things like, "I tested my coils with copper magnet wire and now I am going to test them with iron wire."  The participants in the thread will wait for the results of the test.  If you ignore the slightly different resistances of the two wires, then there is no possible difference between a coil made with copper wire and coil made with iron wire.

It's the same frustration that I couldn't really give a rat's ass about any more.  What does it take to become a master machinist?  Perhaps three or four years of school and then three or four years of apprenticeship?  Do you think a Jow Blow off the street can just watch a few YouTube clips and then start working in a factory machining aircraft engine parts?  Why in God's name do people think they can buy a scope and a multimeter and then research free energy machines?  You saw Chris fall flat on his face because he couldn't solve a circuit that consisted of one lousy component.  Now he has his own thread to teach people how to build allegedly over unity transformers.

So where there is current flow there is a magnetic field regardless of what carries that current?
Mark-What if there was a conductor that can carry current, but no magnetic field is produced around that conductor

Tinman,

Do you know of a conductor that can carry current and yet produce no magnetic field?
