the Ferrocell

[sadang]

Ok, thanks for these clarifications. Now I can narrow a bit my field of assumptions.

After a week they took them off and everything was upside-down! hah

Yes indeed! The habit is the second human's nature!

this pix shows the magnetic flux in a plasma from University studies. See anything familiar?

Hmmm! Is hard for me to understand this image without more details. As you said "We see what we are 'supposed to see". But le me try!

The familiar aspect is the curved purple path, which resemble the curved path of light from the previous image. But I think the analogy stops here! Because in this case we talk about plasma, I rather think that the bent purple path is a beam of electrons instead of light, which indeed will bent in the presence of a magnetic field.

If this is the real case, this purple path is in any point at 90 degree against the path of the magnetic field. This is a very poor experiment and far from the value and the information which a ferrocell can provide.

In a plasma the electrons will be visible in their curved movement under a magnetic field influence, until will lose their energy and will become invisible. More than this to achieve this effect, this setup require a very dangerous to use high voltage source besides many others like, noble gas, vacuum pump, electron gun, glass ball and others. A lot of stuff to reproduce an invaluable experiment which offer few and poor dates about the characteristics of the magnetic field.

Instead, a ferrocell is more safe very easy to use, and very easy to understand how to use it. It offer at a single glance a lot more information about the structure and shape of the magnetic field. And the possibilities to vary the experimental setup at the level of home user, are endless! The same the results and the possible collateral understandings.

I've tried to make use of the electrons beams in analysis of the magnetic field, appealing to a CRT display. It is not a direct interaction as in the case of a plasma ball, rather an indirect one, because I placed the magnet on the glass of the tube and get some very interesting pictures. Bellow are two of them. I have to mention that is a delta CRT tube, from here these starred forms. An old TV tube, will give other forms, but in general the forms obtained will be far from the conventional shape and structure of the magnetic field.

The light ring contains 9 each of red, green, blue and white LED's. Look closely at the previous picture and you can see how the spectrum changed.
White is now yellow. Blue is violet...

In a nut-shell, this cell is making new waves from light and magnetism.

After re-reading my post I realized something that I didn't notice before. Blue does not slow down to make purple (violet).
Violet and deep violet are higher frequencies than blue. This observation is something I have to examine further
this could be the verification I need to compare the ferroparticles actions to negative index materials!

I'll keep you posted (unless someone out there can explain it).

Yes, in the plasma pix, if we could make 36 different points of plasma, each set 10 deg apart, we would see a sphere.
It doesn't appear to have a 'spin-helix' shape, for sure.

While I was experimenting on the Ferrocell, I was doing all of my research with magnets. 
A 1T field is difficult to make with electromagnets. It takes LOTS of power and things get HOT.

In this experiment, I rotate a magnet on the face of a CRT.
The best images (and more accurate) come from a Sony Trinitron.
You can tell if it's a Sony micro-grid tube if the face is very flat and the deflection angle is steep.
The best computer monitors (<dpi) were mostly micro-grid back in the early 90's.

Ok here's a link to a experiment I did 8 years ago: https://www.youtube.com/watch?v=klw8y6ksxj0

Yes, in the plasma pix, if we could make 36 different points of plasma, each set 10 deg apart, we would see a sphere. It doesn't appear to have a 'spin-helix' shape, for sure.

According to my understanding of the phenomena in that pix even if we create 36 different points of plasma, which means 36 cathodes positioned at 10 degree apart in an horizontal plane, we can't obtain a sphere of purple paths in the actual setup, because the lines of the magnetic field are in any point perpendicular to that purple circle. The magnet is somewhere in the outside of the glass ball, placed in a specific position as its lines of magnetic field be perpendicular to the purple circle.

If the cathode placed at 180 degree from the actual one will create a purple circle like the actual one but in the opposite direction, the other cathodes at 90 and 270 degrees will not curve at all or very little their beam of electrons, these latter going in an about straight line. In any way they will not curve to form a circle.

To make each beam of electrons to follow a round path, they have to always interact with the magnetic field at 90 degrees. To get this cumulative spherical effect the lines of magnetic field have to change their angle to become always at 90 degrees for a specific beam of electrons. This can be practically made by:
- a high speed rotary cathode and magnet out of phase by 90 degrees setup
- a high speed rotary cathode and 36 static magnets setup
- a high speed rotary magnet and 36 static cathodes
- a static setup with synchronized 36 magnets and 36 cathodes

And this experimental setup don't show the shape of the magnetic field around a magnet. The magnet is outside in the right or left side of the purple circle. This experiment only show how a magnetic field affect a beam of electrons. To really see the magnetic field shape around a magnet, require a specific experimental setup, with the magnet placed in center of the ball and the pairs anode-cathode placed at 180 degree on the glass wall. All 36 or more pairs of anode-cathode have to be placed this way.

A 1T field is difficult to make with electromagnets. It takes LOTS of power and things get HOT.

Don't even think to waste time experimenting with electromagnets. Besides it is very hard to get one with 1T field density, they require a lot of electrical current and a lot of electrical and thermal precautions in their handling. Not to say they are not the same thing as a permanent
magnet. Not at all!

I know and understand very well the differences between a CRT for PC and a CRT for TV. The main difference for this discussion consist in how are arranged the RBG phosphor colored dots. For my monitor CRT they are in triangle, for your Trinitron CRT they are in horizontal lines forming RGB vertical lines. I don't know if it is fair to open here on this topic an analysis of the colored shapes obtained on an inline or delta CRT using a permanent magnet.

Yes, your analysis is logical. I put that pix up only to show how the plasma goes in a circle with a magnetic field applied.

I'm using electromagnets and cells lately. It takes about 100 watts thru one of these (see pix1) to make a .5 T field for one deflection coil in my EDU to spin the laser beam: https://www.youtube.com/watch?v=XMssut5ik9A 
I cemented them into a thick aluminum housing to keep them cool. this pix is taken before cleanup! (pix2)


I'm sure there is a discussion somewhere on this forum about crt's ! Shadow mask vs. Micro grid.
