Permanent Magnets

Books

GB, I agree, many of the related material is quite expensive. I've been looking at some of the titles "used" from Amazon.

Hi Dean,
i just wanna ask 3 Questions, even when they are may answered.
How much Money did you invest into this Stator, and how much would may cost one or 2 from this Fields.
I guess te complete Device is worth 3000 Bucks? and 2 Fields maybe around 300?
Do you have any 'rolling' in Forces to overcome, even, when it doesnt looks like that there are any
and, how much Force have your Stick when it starts rolling. Is it just rolling or is it still able to move a (small) weight?
Thanks in advantage.

Thanks Dean, those pics really help.

Hi Dean,
thank you for your Answer, the other solution maybe is, to use ceramic Magents, what are way cheaper as the Neodym.
But i do really enjoy the Pictures and Principles of the Track.
Still thinking about, if we can not apply it at other Devices,
because it looks simple, when you can arrange the Magnets, that it creates a Direction of a Force, and leave the opposite Force at the outside, or however you can descibe it.

I think you have people on edge more than anything, I'm happy you have the budget for such setups and to be able to have gone this far.

But how pathetic it might sound, people, or at least me to not generalize too much, are waiting for a closed looped version before they nuke their wallets and replicate this. But on the other hand you can always ask for any kind of help or support in order to attain that goal, and asking is always free. Everyone has some skills, when we share them for the same cause is when we can achieve big things.

Waiting to see

But how pathetic it might sound, people, or at least me to not generalize too much, are waiting for a closed looped version before they nuke their wallets and replicate this.

Roger that. I've been watching this thread with baited breath, eagerly awaiting the results of that beautiful circular version you posted a picture of.

What you're doing looks amazing, I'm still trying to wrap my head around, visualize, what is going on when that thing jets down the track, with all of the various fields inducing currents creating their own fields, it's complicated as hell, maybe impossible, to imagine the interplay of the many vectors.

It looks like you're very, very close to being able to test something with a closed loop. So I'm just waiting and watching. The moment that happens I'll happily drop money into a replication. I'm pretty invested in several other projects, so I'm just watching this one for now.

Keep up the great work, and thank you so much for being detailed in what you've shared. If you have a solution, we all know the world sorely needs access to it.

Additional thoughts

A simple summary. The inducement of multiple forward torque forces, through the careful placement of permanent magnets. Secondary magnetic fields induced by the movement of PMs and Conductors through these flux fields. Plus, the proposed negation of the prominent locking force.

When considering a loop or rotary setup, keep in mind, the interactions of PMs within close proximity of one another that may have a negative influence on the goals.

Another consideration, with a better understanding of these many forces that can be induced with PMs - Consider hybrid designs to further enhance other power systems.

I don't believe you need a circular setup to see tangible gains from this kind of magnetic track--you just need to use some lateral thinking to see the possiblities.

I'm wondering if NdFeB magnets are required to make this work. If not, that would lower the barrier to entry in replicating Mr. Dean's work.

One would only need to build about three complete gates (3x5) with ceramic magnets to discover how dependent this variable is. I would remind one though; the use of metallic PMs in the rotor will be necessary.

Hi Barry,

I think Alnico magnets could fairly be used instead of Neos for the rotor magnets, they are also metallic and not much stronger than ceramic magnets (when ceramic magnets would be used for the stators), hence Alnico seems a good candidate.
Of course I suggest this for those wishing to experiment with this setup but would not wish to spend too much money on this initially. And later when a "proof of concept" has evolved in front of them, the much stronger Neos could come.

My question would be: in your setup the brass cylinders in the stator are also to be made of brass? And these also contain magnets inside?
Supposing brass is not used in the stator but Alu or copper instead, would it introduce drawbacks, just like when brass would not be used for the rotor?

Thanks, Gyula

options

Hi Gyula, I agree, Alnico magnets would be a good substitute candidate for the rotor PMs. It can be done, without the brass in the stator, not quite as efficient. I would not use copper or aluminum as a substitute in these tubes. Better nothing at all.

The ideal combination that I found to date is: brass rotor and brass throughout stator interior, copper rails for stator. I have had success with aluminum rails and rotor, just not as good. The specific brass is a K&S product out of Chicago, found at many hobby or home improvement stores. The wall thinness is what makes its selection best. Too much mass seems to be an issue in any of these components.
