To all:

Anyone involved here good with FEMM-4.2 or some other "magnetic-simulation" software? Maybe we could get an idea about the potential of the magnetic-beam.

I'm not any good with it yet. . . . .  ???

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.

Mr. Volland.....

 ;D great  find. I will elaborate on this back at our heretical place.

@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.

It looks like it would have very little area where it might stick.  With a small amount of momentum, it looks like this might work.

@Jerry:

I think that there is only 1 "sticky" spot in this arrangement (see following picture) and it appears like there would be sufficient "push" to get past it. However, I don't know how to calculate or simulate the experiment with the software I have.

I am running a magnetic simulation as we speak, however I do not believe that the the "graph" that has been shown is correct, ill post results and pictures when done,

the key aspect of this is variation from the inverse cube law with respect to the "beam"

Thanks for your help ~ I look forward to seeing your results on this.

Hi All,

I've been busy with the holidays and family coming to visit.

In the wheel setup I still think it will still find a sticky spot on the edges. I'm wondering though if instead of having the magnets perpendicular to the control magnet, angle them back 45 degrees on the sphere. It would look more like an arrow but the south facing field would be toward the back.

Hi Tak,

I used a steel ball bearing for the sphere. The magnets are directly pushed onto the sphere. The ring magnets are from K&J Magnetics http://72.3.133.7/proddetail.asp?prod=R636 . These have just the right inner diameter(3/16") to fit on the standard Lego shafts, which hold it in place. I have not tried a cube yet but might be interesting.

Hi Armagdn03,

I would be very interested in seeing the output of the magnetic simulation. If you have time could you try to simulate with the outer magnets swept back 45 degrees? Thank you.

@DreamThinkBuild:

Not sure if I followed your idea on rotating the magnets. . . . Is this drawing sort of what you had in mind?

Some preliminary photos for visulization (2d)

These are a 2d version of the original array,

and an "improvement" where I cut off the pole at the bloch wall, seems to get better results.

@DreamThinkBuild:

Oops! After re-reading your post I realized that you were addressing the magnets in the "beam" array. My bad. . . .

Is this more like what you had in mind??

Hi Truesearch,

You got it. Make them 45 degrees so it minimizes the south pole influence.

Hi Armagdn03,

Thank you for the simulation images. The design of the Leedskalnin beam amplifier is really great. It looks like all the coils are series wound. Any other information on that build?

Looking @ that vizimag pic, seems like your lens is an incomplete halbach array? You can do some really interesting things with them!

i think the kogging will still happern ethern with a magnetic beam but i feel that the kogging would be greatly reduced because of the distance between the magnets

To all:

The simulated-flux field posted by @armagdn03 doesn't seem to reflect the experiments done by @DreamThinkBuild. I'm not sure what this tells us. ??? Perhaps Vizimag isn't calculating this design correctly as it is a 2D program and this is a 3D array.  :-\

@DreamThinkBuild, do you still have your "lego" build of the array? How difficult would it be to assemble a wheel with several magnets in repulsion on it and see what happens? I mean, if your time permits this.  ;D

Currently I'm not setup to do any experimental builds  :(
