Magnetic 'Lens'

[DreamThinkBuild]

Hi Truesearch & Jerry,

I can only get a rough estimate of what the flux map feels like by dragging a flat magnet over the top. A large sphere will create a dome like beam and a smaller sphere will be tighter. There is a falloff it's not like a laser beam. Six inches was the falloff of this but the signal to the air core coil was weak.

The smaller the sphere the harder the challenge in getting the magnets to cooperate. You need, like in the patent, to have metal shafts or bolts so the magnets are away from each other but still linked to the sphere. If they are too close the magnets want to twist and snap together which provides many hours of enjoyable fun.

In your picture of the wheel you may need shielding on the edges of the magnet. When I take the flat magnet and place it anywhere near the edges it wants to snap down to the south sides of control magnets.

I drew a picture to show what the beam looks like this is just from passing a flat magnet over the beam area. The outer edges attract as you get to the center you can feel a noticeable push/repel up on the magnet. As for stretching I'm not sure, maybe with another ring of magnets around the beam area you could make a focus control.

@DreamThinkBuild and @Jerry:

After seeing what you've posted and getting a little better grasp of the "possible" flux field/lines I wonder if the following magnetic "wheel" would potentially work. Look it over and see what you think.

A couple questions if you don't mind.

1. The patent makes no mention of what the focus sphere is made of, but it does say the connecting
bolts are nonferric. Have you tried a nonferric object to see if there is a difference?

2. If a ferric focal point works best, which works better, a sphere or a block?

thanks for any thoughts to these,

Why go thru all that work? 

Just get an old CRT PC Monitor & bust the neck part off the CRT.

Presto, you have an Electron Beam Gun, all FOCUSED & READY TO GO.

@Fatbird . I am not sure that a magnetic beam and an electron beam are the same thing . Also once the tube looses its vacuum , the cathode heater [filament] would burn out if energised .Nice idea for all that .
