So, WHY THEN SAME POLES OF TWO MAGNETS REPEL AND OPPOSITE ATTRACT??

Any ideas and explanations you may have?

N and S spins are opposite directions, even if you don't see the pattern.
It's like trying to screw a right-threaded nut on to a left-threaded bolt.

Nice pix, BTW.

Exactly! however is there a way to prove it optically on the ferrocell without using a CRT?

Excellent dipole Halbach ring array with only one pole radially magnetized!



Excellent dipole K=2 configuration Halbach ring array field shown by ferrocell done with 8 magnets (see where the arrows are).

There is one normal pole at the center of the ring (i.e. black hole at the center) and the other pole is the radial magnetized black thin ring shown.

Its like an radial magnetized ring magnet but only its outer perimeter is magnetized radially all around and its other pole is an normal pole at the center of the ring!

And related to Mikes awesome tank experiment:
Something similar that's not common knowledge is a sphere magnet will levitate in a ferrofluid.

If you fill a small container with ff and drop a sphere into it, the magnet will move to the center and remain in that position.

What?!!... That defies gravity!! That is also proof that ferrofluid is magnetically isotropic.

You really need to read that book on Ferrohydrodynamics by Rosensweig. It has many answers and a lot of questions, too. It's the Bible of Ferrofluid.

Looked like a great reference. I was able to read some at the beginning on a free sample web page. Then tried to scroll down to p.150 but s.o.l. Ended at p.132. You know a free on-line source or do I have to buy it? Or check the local library... fat chance they'd have it.

I doubt there is a legal free download. I saw used paperbacks starting around $18.00 usd, but you may find a copy at your local library (remember them?).
Anyone seriously interested in Ferrofluid should have a copy. It's the 'worlds reference' on the subject.

Spinning Plasma ball experiment!





Makes you realy wonder what magnetism really is?...

...a spinning inertia plane (i.e. dielectric plane or Bloch disk) maybe?...

Timm here is the 3rd confirmation from plasma experiments

These results do seem to correlate with my early experiment. Now all we need is a 3rd verification using plasma. It should present the same views.


Gotta go. Good luck in Utah, Ken. Have fun.
This little gem although his narration is partially wrong in some points and totally wrong at some other points:



The ion current on the Mobius glass walls flows at the down direction V vector towards the exciter platform. He is using a cylindrical magnet on a cylindrical glass.

When he inserts the pole of the magnet inside the the glass at the center, magnetic B field is parallel to V vector of ion plasma current and the right hand rule therefore results to no Lorentz force is applied to the neon ion current according to classical theory with magnetic flux lines coming out of the North pole and going into the South pole . However we see definitive CCW spin for North pole and CW spin for South pole!! Right hand rule does not apply here!

How is that possible? Unless field of magnet is not static but consists of two counter spinning torus fields as shown by the ferrocell?


Also from primer fields video, the two torus field geometry is also demonstrated with plasma experiment:





Pause at exactly 7:27 time of the above video.

Brightness of the plasma prevents to view the two separated magnetic fields in most of the video however at that time stamp above they are evident.

BREAKING NEWS!! (UPDATED) Total complete Quantum Field of dipole magnets shown by the ferrolens

(important read description on video)



A diametrically magnetized ring Halbach magnetic array was used and the 100 mm demonstration ferrocell from Ferrocell.US . The 2mm more sensitive side of the ferrocell was used.



This is a repetition of the back at 2007 experiment done by Timm Vanderelli, inventor of the Ferrocell but this time a more advanced ferrocell was used fitted with a LED light strip to obtain the more detailed and higher resolution wire-frame pattern of the magnetic flux imagery.

Old classical experiment of Timm Vanderelli (he used a cylindrical magnet therefore confirming that the below geometrical field pattern is the same for all dipole magnets independent their physical shape):



Also keep in mind that there might be some distortions present on the field image due the fact that a magnetic array of 12 individual magnets was used instead of a monoblock diametrically magnetized ring magnet.


Technological Educational Institute of Crete 2018

Field viewed with the 2 mm, sensitive side of the 100mm demonstration ferrocell




also part 1 of video:
Field viewed with a magnetic field viewer film.



and part 2:
Field viewed with the thick 6mm side of the demonstration ferrocell adding more depth of field information.



...more to come...

... some more observations and comments



Frankly, the above picture when It first came out on the ferrocell scared me.

It's an eye. The eye of Mortar from Lords of the ring maybe?

Seriously, we can observe clearly above the split on the edges between the flux of the two separated pole fields. Specially observe the black halo on the outer perimeter of the ring and how it suddenly breaks at the middle where the dielectric plane or else Bloch region of the magnet is.

The two torus hemispheres stucture of magnetic fields is evident.

Also bear in mind that this is not a monoblock magnet but an array of 12 individual cube magnets so the field is not perfect and some distortions will be present.

Specially the inflated melon shaped Bloch region was also evident on the magnetic viewing film and magnified even more later on by the ferrocell. I believe this has to do with the fact that I've used an ring array instead of a monoblock magnet.

Fortunately, I have found and ordered diametrically magnetized monoblock rings and expect them to come in a few days.

Also the funny black smileys figures on the two pole of the magnet up and down instead of the oval shaped image we are used with from other type of magnets is normal I believe since remember the total dipole field is confined here inside the ring and we get the total 100% side view of the two torus fields on the poles. So center of poles are appearing more like a torus than an oval. Of course there is also some image compression of the image on the ferrocell surface present.

Further, on the peculiar straight parallel flux lines getting expelled out from the edges of the above figure. The answer for why is that? Is I believe, because they have to!...



...The theta geometrical pattern θ, of dipole magnetism repeats like a fractal and expands to 3D space forming overlaid repeating shells of the same pattern up to the radius of influence of the magnet forming at the middle the total Bloch axis of the field of the magnet. It's like throwing a stone in the calm surface of a pond making overlaid rings.

In the next days I will post more pictures of the observed field zoomed in at critical regions.

Please feel free to comment and make observations on these results and if possible to replicate the experiment on your own and share.

We need to brainstorm. That is also the main reason why I am posting my results here. I need your input.

Kind Regards,

EM

Magnetically 100% controlled light polarization by the ferrolens




This experiment proves that the activated (i.e. magnetic field applied and lighted up) ferrocell light polarization (i.e. lines we see on the ferrocell) are 100% controlled and aligned with the flux of the external applied magnetic field.

Therfore the ferrocell shows 100% the flux directions of an magnetic field and magnet.

An inactivated ferrolens does not polarizes light. Only when it becomes activated with an external magnetic field applied. Thus showing that the image we get with the ferrolens of the magnetic filed applied is 100% controlled by the applied field and in total accordance with this applied field and its flux directions.

Diametrically magnetized ring magnet - Total separation of the polar fields



Half of the ring magnet is one pole of the magnet and the other half the other pole of the magnet. We see in the ferrolens a dissection at half of the total 360 degrees field of the magnet, side view.

Notice the total separation inside and outside of the ring of the two toroidal pole fields of the magnet. Suggesting two separate monopole polar fields since there is no flux observed going directly from one pole to the other.

Transparent pole field view of two magnets attracting placed under and above the 509



One of the advantages of the new 509 Ferrocell is its great optical transparency which allows you to see images like in this video.

Important still photos from the 509 Ferrocell experiments





...more photos here:

https://drive.google.com/drive/folde...K1?usp=sharing

I used the 509 cell and a 10mmX40mm cylindrical N40 magnet.

I intentionally bought this relative long cylindrical magnet to achieve more polar separation and I was right. It shows up in the pictures. I have coated the nickel plated neodymium magnet with a black plastic pvc to cut off reflections.

Again we see that one arm of the theta pattern is more prominent and brighter as if the flux is coming out of the ferrocell towards the observer on that arm whereas on the other arm is sinking in to the ferrocell. In some photos the dimmer arm is missing!... I believe that this is an indication that the Bloch domain disk together with the two torus polar fields are all spinning CW, side view with North pole located on top of the picture.

Light Led was 2cm under the ferrocell. No special adjustment needed to the camera distance and angle to obtain the pattern. It popped straight in front of me.

Also see some still photos in the second folder of the diametrically magnetized ring monoblock magnets experiment.

Funny enough the total separated polar flux does not show in the still photos (contrast issue I believe) but shows on video on the video capture photo inside this folder.

The theta pattern with one arm more brighter than the other shows also in the diametrically magnetized ring magnet photos if you look closely.

EM
p.s. can help it to notice , in the second picture of the outline of the the field of the cylindrical magnet side view the striking resplendence (only reversed) of the polar fields shown in this picture with magnetic pods used by David LaPoint on his "Primer fields" experiments youtube series:

Field of spherical magnet as shown by the ferrolens quantum optic device -theta arms


Photo 1 legend: Spherical magnet North pole is up and South pole down. Bloch domain wall disk at the middle of the photo. Nanoparticle chains stacks in the ferrolens showing the expelled theta θ arms of the Bloch domain wall disk of the field at the middle of the sphere magnet and its lower South pole hemispherical field region tangent to the the Bloch domain wall disk.Notice how the chains stacks on the theta arms left and right appear to be bend outwards like straws bend by the wind.


Photo 2 Green circled areas above indicate what part of the magnetic field wee see in previous shown photo 1.

Censorship of Ferrolens wikipedia

Hey guys,

I just noticed that the article on english Wikipedia describing in a few lines what the "ferrolens" is has been deleted.... I see it when I google it, but cant access its content anymore. It says doesnt exist. Some censorship going on? Just wondering, I wouldnt be surprised by such actions. Censorship of truth is a real problem of nowadays, one just have to look at Wikileaks and what they are doing to Julian Assange

https://en.wikipedia.org/wiki/Ferrolens

https://en.wikipedia.org/wiki/Wikipe...tion/Ferrolens

Who ordered to delete it?

Wow... I complained at wikipedia for deleting the ferrolens wiki entry, now one day later, my IP is permanently banned. They did not even make a comment about my complains, nor defend their position or anything in that matter. How pathetic is that... That just motivates me to sue them for intential scientific and communication suppression.

It says doesnt exist. Some censorship going on? Just wondering, I wouldnt be surprised by such actions. Censorship of truth is a real problem of nowadays, one just have to look at Wikileaks and what they are doing to Julian Assange

Who ordered to delete it?
Interesting.

I'd like to hear from Markoul about the Wikipedia deletion.

Ferrolens
A ferrolens or ferrocell is a type of superparamagnetic optical device which can display magnetostatic or dynamic magnetic fields in real time and in color. In other words, it is a quantum optical magnetic flux viewer. [1][2][3][4][5]


Quantum field view (Video) of dipole magnets as shown with the ferrolens.[1][2][3] (a) Pole wire-frame field view of a ring magnet. A LED strip lighting is used. (b) Outline side field view of a cylindrical magnet. A single small incandescent lamp is placed under the ferrolens.
For its operation it is using a thin film of ferrofluid encapsulated inside a lens similar to a Hele-Shaw cell filled with ferrofluid.[2][6] Usually the ferrolens is fitted with a LED strip light programmable source on its periphery emulating different lighting conditions. The superparamagnetic nanoparticles inside the ferrofluid are following the magnetic flux of an external field induced into the ferrolens (i.e. a permanent magnet placed on top or under the ferrolens). At the same time, the oriented and aligned with the magnetic field lines nanoparticles, are emitting back part of their incident light (Video) thus essentially allowing them to "paint" the magnetic field lines and therefore making them visible.[1][3][4] Light intensity and color texture of the field lines shown can vary slightly accordingly to magnetic field strength and direction.

A ferrolens has advanced visualization capabilities in detail, spatial resolution, sensitivity, color information and can depict also depth of field information on an observed magnetic field essentially making it a 3D holographic nanomagnetic direct observation passive device for magnetic fields and related quantum effects[1][4]. Also when the ferrolens is used with a LED light strip, it shows the wire-frame model of the individual magnetic flux lines of a static magnetic field.[1][2][3]

Currently, it is the only device, reported by academia of this type which can efficiently visualize fast changing (i.e. dynamic) magnetic fields[4] and its superparamagnetic properties is allowing it to display the quantum field of magnets.[1][2][3]


Magnetic field of transmitting radio antenna rod as viewed by the ferrolens.[4] Metal frame of rod becomes transparent under magnetic viewing (i.e. invisibility cloak). Video
Further academic research is also carried out for these type of devices for the polarization of light using magnetic fields.[3]

A ferrolens is not to be confused with a FLCD display device or magnetic viewing film, since their technology, operation and applications are different.

Ferrolenses are available today mainly for research applications and education in general, under the registered trademark Ferrocell[5][7][8] as a patented product. Many Youtube videos are available with “do-it-yourself” instructions for making ferrolenses for personal use. Video
