fun observations about the magnetic field

What 2 inch neo sphere are you talking about?

We use a lot of large and heavy 37mm balls (from a radial bearing)  and used some strong magnets as spokes and bearing points

No "neo sphere" is mentioned. And 37 mm is only 1.45669 inches.

@TinselKoala,

Substituting neo sphere magnets for the steel balls is my idea. The center ball would remain Steel. The stacked magnet axles would serve to keep one pole facing out, and pivot on the center ball. The magnets and steel ball can be any dimension, as long as they match. 2" is the largest size neo sphere's come in currently. Way over budget for you.

Plastic "Bubble Blowers" with  handles and circular loops, could be glued to the center Steel ball by the handle ends and placed over the Spheres, to keep the "Neo Magnet Spheres" apart and secure against parting from the Steel ball. Maybe the spinning balls will reduce "Lenz Drag"

I'm afraid there is nothing special about these videos. The experiment with the CRT screen and its behaviour in the precence of a magnet is predictable. The electron ray fails to hit the right color, and instead are deflected by the magnetism. Also this electron ray is moving horizontally very fast and its magnetic field will respond to the field from the magnet and cause the screen to swirl.

Is not about the colour, but the "swirl" as you say (the shape). The very first video proves at min 3:20 the spiral motion of magnetic lines, thing which is not presented in any school books.
Sure one could bring into discussion any of the theories behind cathodic tube, but that won't explain WHY that shape occurs. I take the "electrons" as a finer grade of iron filings and if not convinced, here you have another experiment proving the same:

If you could accept that, then you could accept some other major aspects of that video.

Regards.

The electrons are moving charged particles, which will travel in curved paths when passing through a magnetic field oriented in certain ways. This is fundamental, it is entirely calculatable, it is contained in Maxwell's equations, and it is how the CRT designers make the electron beams hit the right places in the face of the CRT when it is displaying an image. Have you ever taken apart a CRT monitor/TV set? Do you see the yoke coils and the fine tuning magnets around the neck of the CRT tube? All this stuff about how electron beams behave in the presence of magnetic fields is QUITE WELL UNDERSTOOD or engineers wouldn't be able to design the CRT in the first place! The reason the "spiral motion of magnetic lines" isn't presented in "any school books" is because it doesn't occur in reality. Your mental model of electrons as "finer grades of iron filings" is also wrong. Electrons are _electrically charged_ particles and iron filings aren't. Moving electrically charged particles produce a magnetic field, and the direction of motion of electrically charged particles is affected by external magnetic fields. These are facts that are proven by literally hundreds of engineered devices that you encounter every day, including the computer that you are using to read this comment.
