Magnetic 'Lens'
« on: December 16, 2010, 09:11:31 AM »
First post, so take it easy on me!  :P

I was reading up on Electron Microscopes, and read about the way they direct the electrons is through a magnetic lens of sorts. The magnetic force drives the electrons through a small gap, blah blah..

any body have any thoughts on focusing the magnetic field instead? sort of taking the field and condensing it, so that it's stronger or more condensed? Like focusing light down to make it brighter?

Just a thought..

Patent #5929732 shows a focusing assembly for making a magnetic beam.  The claim is that when focused in this way a small magnet's field will have an effect on the colors of a monitor's screen from a distance of a few feet.  It's also claimed that the focused beam can transmit electrical power.

By "focusing" the magnetic field would this have the same effect as "shielding"??

This doesn't really shield the magnetism, it just squeezes into a beam.  At a distance this might be almost as good as shielding since shifting the beam a small angle would move it from the region of interaction.  There's also the question if a repelled magnet at a distance would produce a counter force on the focused magnet.

As far as I know the only things which will shield magnetism are a superconductor or a plasma.

Hi Truesearch,

Welcome to the forum.

Hi Jerry,

I built patent #5929732 last year. It's a really interesting device. If you take a square magnet and run it over the beam area you will notice a push in the middle. A larger steel ball will make a larger (dome like) falloff of the beam. A small steel ball beam will make the beam narrower (pinpoint).

The magnets are pretty weak and it still put out a good beam. I wrapped a coil around the top magnet and pulsed it with a square wave into a air core coil it does pickup the signal, about a half foot away, on the scope. I was thinking of removing the top magnet and putting a iron core with a control coil to see if I could make a pulsed magnetic switch but never got back to it, so many projects, so little time.

If you could either focus or reflect magnetic fields then you could create a magnetic motor. From all my experimenting I haven't found a way yet.

Here are some pics of it.

Hi DreamThinkBuild,

That's a good looking build.  Glad to know the patent is valid.  I wonder if you put an opposite polarity magnet into the beam if you could stretch the beam by pulling the magnet back?

I'm a firm believer in magnetic motors.  We just need a shield or reflector which doesn't require more energy than can be obtained from the motor, or produce too much repulsion while being slid into place.  Field switching also seems to be a good approach.

@DreamThinkBuild

That is a nice looking concept build!

I'm trying to understand what the flux "field" or "map" would look like with this magnetic lens/beam. Got any ideas?

@DreamThinkBuild:

How "tight" or "focused" is this magnetic beam?

I was wondering if something like this rough diagram might work. It's simply a wheel with magnets situated around the edge at an angle so that the magnetic "beam" would push against the face of those magnets for rotational movement.

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.

Hi DreamThinkBuild,

Those graphs look pretty interesting.  Since the blue sides of the magnets on the wheel would be attracted at the edges of the beam assembly, then repelled closer to the center, the question is if the wheel will rotate from one area to the next on its own momentum.  If not, the switching coil could provide a little help if pulsed correctly.  The gambit is whether the pulse energy can stay below the output from the wheel.  The beam angle might need to be adjusted, with the spacing also touchy.  What are your thoughts, having felt the relative strengths of the effect?

@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.

@DreamThinkBuild

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,

tak

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 .
