I would dearly like to see a real life device that show's a current flow with 0 volt's. Even a super conductor is not absolute 0 in resistance. So where there is a current flow across resistance(no matter how low) there will be a potential difference.
How can you ever have current without P/in?. I meand 10,000 amp's at 0 volts=0 watts-ohms law.

That would be a permanent magnet then.

From what I read superconductors absolutely do have zero resistance - that's the whole point. But, they usually also have a counterpart current which does follow ohms law. So the conductor is simultaneously operating in 2 different modes... It is pretty wierd.

To get current into a SC - you have to do it when it's not in the SC state, then cool it until it switches - then - I think you still have to supply the conventional current part - although it's very small... Perhaps someone who knows more will comment.

It's not such a stretch of the imagination is it?
- Pure voltage = Electrostatic Field
- Pure current = Magnetic Field

What about this weird magnetic effect discovered by Wesley Gary ?

WESLEY GARY NEUTRAL ZONE

The neutral zone is a neutral line where the polarity of an induced magnet ceases and beyond it changes polarity

I have seen some videos and it seems to refer to two repelling magnets which get attracted to each other when they are put closer and closer. The original effect seems to be done and tested in horseshoe magnets.  As far as I have seen with bar magnet shapes it seems to need sticking a iron bar to one of the magnets.

I've tested Wesley Gary's principle with a coil hooked up to an oscilloscope.

If there's a point where the field flips polarity - it should give a spike of voltage thru the coil. Wesley Gary designed a generator based on the principle.

I couldn't find a point where the field flipped, but it's an easy experiment for anyone with a 'scope (they're cheap), and it's quite possible the failure was mine...

Tim123:

If you can point me to a source of information which explains: *how a magnet works * - as opposed to: * what it's behaviour is * - without using self-referencing terms like 'magnetic domain' or 'magnetic moment' - I would be most grateful, and will read it immediately.

Perhaps your question can be posed another way:  Why does a moving charge produce a magnetic field?  These clips might not answer why, but at least they answer how:

Anyway my advice is that before you ask the "big questions" learn the answers to the small ones.  I think it was you that stated that sprinkling iron filings is no good because it will disturb the magnetic field of the magnet.  In fact that is not true and I am not going to get into splitting hairs.  My guess is that you "made a pronouncement" without the necessary knowledge to truly know if what you were saying is true or not.  That can be dangerous sometimes.

As a disclaimer I am not in any way trying to implore you to learn about electromagnetics.  The simple advice is to try to be conservative.  I don't see it stated much any more on the forums, but the line "this is research that is outside the realm of electrical engineering" is normally a laughable joke.  It can be frustrating sometimes to read it but who really cares.  "Cold electricity" and "radiant energy" are classic examples of the downright foolishness.  What's sometimes frustrating to me is that con artists use these terms to get money off of people.
