Here's the thing about the iron fileings.
In order for them to carry a magnetic field,there has to be one there in the first place.

Another thing to concider is this-if at the (so called)bloch wall,the field is null,then when we place say two 2 inch x 1/2 inch rod magnets together N to S,why dosnt one just drop off, if at the center of the two is a null field?-as the two magnets have just become one long one.
Infact,it is extreemly hard to sepperate those two magnets,and that can only mean there is a very strong field at the center of the magnet-not a null field.

For Tim123:  Let's put the "extra dimension" notion off to the side for now.  Our senses and standard measurement apparatus are perfectly capable of explaining the phenomenon in the clip.

Hi MH :)

I dont think this is true. As far as I'm aware, physics can only describe the effects - it has nothing to say about the causes.

The vid you posted - they have the 'Left & Right-Hand Rules' - describing the motion. But no real idea as to * why * that occurs, only speculation. Current physics is * totally incapable * of explaining magnetism in general... At least it was the last time I checked... ;)

Magnetism * is * a mystery - as is all of physics if we're honest - that still remains to be revealed. People only * think * they know things...

If we ignore the extra-dimensional stuff when dealing with reality - then all we'll end up with is an approximation.

Regards
Tim

Lol. Can't fault the logic.

I think the Bloch wall - from what MH was saying - is a special case where two * opposing * fields meet in a non-premagnetised ferromagnetic material. He described it very clearly.

The 'null' field at the center of a magnet must be a different phenomonon. It's not a Bloch Wall. It should have it's own name.

But it's not really null - there is still field there - as TM pointed out the 2 magnets will hold together. If you cut a magnet in half in that orientation they'll stick together.

Something happens in the middle of a magnet - and it looks like the field 'flips' polarity. But if you had 2 separate fields it would look functionally the same to us - given our measuring equipment...

Perhaps the magnetic field - current spiralling in the 4th+ dimension - appears as an 'N' to us in one half of the cycle, and 'S' the other.

I once placed a wind up watch near the center of a magnetic field to see it's effect on time.  As I slowly approached the field, I noticed time slowing.....then the watch stopped!  Time apparently stands still in a magnetic field!  It seems to have had a permanent effect on the passage of time in the immediate vicinity of the watch as well, because other watches that come in contact with it, have slowed to a stop as well.  I will buy more watches and keep you all apprised of my discoveries.....That is, provided I do not get sucked into the future and smash into a bloch wall at relativistic speeds.

Lol-nice one Tech,place a magnet near a time keeping mechanical oscillator,and wonder why it slows or stops lol.
Maybe try placing a magnet near a sun dial,and see if the shadow slows or stop's?.

One has to wonder about that magnetic current you talk of Tim.
A direct current can produce a magnetic field,so why cant a direct magnetic field produce a current?.
Oh wait-it can-the N machine.

LOL.....I actually fogged up a sun dial with bose-einstein condensate once and it took a little while for the shadow to appear.  (I kid.  It wasn't bose einstein condensate but it did fog up the sun dial until the magnifying glass in my back pocket ignited the cloud and my future flashed behind my back.)

The theory is developing...

I have always felt that the 3D space we're in is *not* the 'real' universe. I've always felt that distance, and space was an illusion.

Modern physics treats this 3D space a a fundamental part of the universe - and they assume it's rules are universal laws.

My feeling, as I've said, is that all we see is *effects* and never the *causes*, and if fact this entire 3D universe is an effect caused by something in the dimensions we can't see.

I think that distance and separation are effects caused by the creation of dipoles in the *real* dimensions.

So I hypothesise that:
 - the electrostatic field is like the 'primary dipole', it is 'voltage' or 'potential' and it is the first spatial dimension.
 - the magnetic field occurs when current flows between the two potentials. It is the second dimension of space.
 - the gravitic field is the 3rd dimension, and it's caused by ... the change in angular momentum of the current, I dunno yet - something like that...

But all these 3 things are just aspects of the same thing - the 'universal dipole'...

So the 3 *apparent* dimensions we see are secondary effects caused by the fractured way we see the universe.

The question is: How many *primary* dimensions are there? I.e. the ones we *can't* see. I'm working on the hypothesis that there are two, maybe three...

Yeah, I know it's heavy. Not exactly sure why I'm suddenly thinking about this stuff - but hey, why not...  :D

One has to wonder about that magnetic current you talk of Tim.

It seems absolutely clear to me that a permanent magnet has current flowing though it - permanently - with zero volts.

Just like an electret has a constant electrostatic field - with zero current.

The question then becomes - how the heck can it do that?

The answer is - by having more dimensions than we can see - and in those dimensions the material behaves like a superconductor does in ours.... :)

...and those dimensions appear as spirals / vortextes to us - which is why the experimenters Hanon mentioned found vortexes of field lines.

@Tim
You cant have current without voltage,even if that voltage is low,it is still there.
Current is carried by electron's in electron flow. For there to be a flow of electrons,there must be a potential difference (voltage).
You can have voltage without current,but you cant have current without voltage.

Tim123:

Why not just look up how a magnet works instead of speculating about extra dimensions?  You are illustrating the classic problem with the forums, and that is to speculate about things without having mastered the fundamentals.  That clip with the magnet in the water and the swirling bubbles is another good example.  That guy talks about an "amazing discovery" but he clearly doesn't have the slightest clue that moving charges will be deflected by a magnetic field and that explains the infamous vortex.

Tinman:

You can have current without voltage.  The classic example is a superconducting ring - an inductor.  Yes, people will be dismissive of that because it's too esoteric.  But like I had a debate once with Farmhand where people get all upset when you talk about ideal inductors but are just fine with treating their capacitors like ideal capacitors.  You can have a voltage source without any current flow and you can have a current source without any potential difference.

It might be that a current source with no apparent voltage difference is something that you won't see often in real life.  It doesn't matter, you see approximations to it in real life.  Perhaps more importantly, current sources are used in electronic circuit design all the time and your typical bench power supply with 10-turn knobs for the voltage adjustment and the current adjustment can be configured as a current source just as easily as it can be configured as a voltage source.

Hi MH :)
 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.
