Roy Davis and Rawls Magnetism Discoveries

[tinman]

If you look at the field lines of a PM or EM,what you call the bloch wall ,is only the weakest part of the continuing field. Where the field lines are tightest or closest together,is the strongest part of the field.This is actualy inside the magnet itself. But as we cannot use that part of the field,the next inline is at each end of the magnet,where the usable field has the tightest field line pattern.
The center part of the magnet,has the widest or weakest field line arangment,so the field is weakest at that point. This is the point you refer to as the bloch wall-but there is no wall at all,or break in the field-but only the weakest part of the field.
So if you place a piece of flat steel in the center of the magnet,standing on edge,ofcourse it will feel as though there is a nutral point,as the steel  will be getting pulled toward each end of the magnet with equal force.
If some one is pulling on your left arm with 10 pounds of force,and some one is pulling on your right arm with 10 pounds of force-which way are you going to go?

If there was some sort of neutral point or bloch wall,then it may look something like pic 1 below.
But as you can see in pic 2,there is only continuing field line's-no bloch wall to be seen.

This is were you would find a Bloch wall:

[N-----S] [Iron Bar][S----N]

There would be a Bloch wall in the center of the iron bar and it would have some thickness.  There no such thing as a Bloch wall in free space.

What is the true topology of the North & South magnetic fields?

There are no separate North and South magnetic fields.  That's simply a naming convention.  That might be the root cause of the misunderstanding.  Magnetic fields are loops with no beginning and no end and no North and no South.  If you can understand that (see Tinman's clip) then that leads to understanding that there is a smooth continuous magnetic flux through a bar magnet.  You can imagine it's like the bar magnet is a small rectangular wind tunnel pushing the air through in a nice linear flow.  The air then circulates around the room and then goes back into the entrance of the wind tunnel.  That's what magnetic fields "look" like.  Do you see two different kinds of wind?  The answer is you don't.  What you do see is two different directions for the same wind.

Hllo Folks,


lets get some of facts straight:
http://en.wikipedia.org/wiki/Domain_wall_%28magnetism%29

A blochwall is a transition-line ( area) between the spontaneous magnetisation areas of a ferro-magentic material ( not magnetized ) and is not a fixed local entity. See the picture of a magnet with the sections A-B-C. The fieldlines of the elemtary magnets are spinning 180 Degrees in the center of a bar-magnet and oriented in the direction of the viewer...and this means then that the outer field is twisted....and  they do not add up to zero. Blochwalls move if an external field is exerted to the material and can even disappear if all domains are alligned in a solenoid-core.
And of course if you split a magnet into two, a new zone B must be created.
In the german part of the wiki you can find a more detailed picture ( HT-HT ) which shows the effect of the moving Blochwalls if an increaisng external magnetic field is exterted

http://de.wikipedia.org/wiki/Weiss-Bezirk

The difference between a ferromagentic material ( not magentized ) and a permanent magnet are the angles of the fieldlines of the random domain-structure versus a forced two-domain-structure.


Hope this helps

Hi,

My aim with this post was to show these discoveries. I knew that some people will be open to discussion and other people just won´t accept it. Please don´t kill the messenger. I just ask you for reading the two books and LATER discuss if they make sense or nor. We can not say "no" because it has been "no" for a century and a half. Howard Johnson and, Roy Davis & Rawls worked with magnet for many decades. The wrote those two books to compile their findings over that time.  The book written by Roy Davis and Rawls,Magnetism and It Effects on the Living System, was not uploaded into internet. I had read about it but it was not accesible on the net. I bought an old edition into Amazon used books and I scanned it in order you could have access to that info.

I already know of another researcher, Marcos Pinel, who built a theory stating that the center of the magnet was a point of null magnetic field. The image below was done (not by me) with a magnet in front of a CTR screen.

I just ask to study this information, not just read my initial post and in 5 minutes reply because it sounds weird. Take into consideration that those books are a serious work done over many years of researching. I am just exposing that info for people who could take profit of it.

Regards

Hi Guys, thanks for the replies. I get the Bloch wall idea now. I'm tending to agree with you, but open minded to both ideas ATM.

There's definitely more to magnetism than the standard science acknowledges - it does have a spiralling component - for example. Eddy currents are interesting things...

Tinman, I've heard argued that the traditional image of iron filings on a magnet is not a true representation because the filings act as magnets too and distort the field. It's possible...

The thing is - none of us can actually see it - and it's virtually impossible to test - unless you can find a material that's only attracted to one polarity...

Also, you have to bear in mind that we're only able to experience the 3 dimensions of space plus time, which I don't think is where the action really happens... 3D spacetime is a projection of a more fundamental reality...

Hanon, don't be too sensitive to the critics, but do listen to them. Sometimes they're right, but not always.

What you see on the CRT screen is not a picture of the fields - it's a picture of what the fields do to electrons. I'm not sure it's possible to draw any conclusions either way from it.

You have to admit that it's a little wierd - in the standard model - how the magnetic lines of flux switch between one polarity and the other at the mid-point...?

I mean - it can't be that the fields 'cancel each other out' can it? There's only one field. How can a single field cancel itself out?
