Hi guys, I have been following this topic online for years, facinating stuff. This looks promising magnetman, well done. I'd love to have time to play around more with this one day. Will get some things together. I have a small workshop and cnc router so will make some parts. I was wondering if the rods could be rotating? Picture two donuts squashed under weight as they are stacked together. The gravity is constantly pushing the flux lines up rolling into the centre of the donuts. Toroidal flux lines. So the rod is like a surfer on an endless wave. Rolling over the flux line surface endlessly trying to fall into the centre and the 45 degree causes sideways drag? I don't know, just thinking out loud. Maybe it has something to do with Poloidal–toroidal decomposition?

@Tom,

Your description of the motor's power is really mind blowing! You realize that you are unleashing a Tsunami high on the Richter scale with your disclosure? A pivotal event in history.

The single rod magnet inside the plastic tube is very powerful when directed downwards into the 45 degree frame work.  I am going to try another idea I had to make the setup speed less.
Instead of using a single rod magnet. I am going to use a string of  9 mm “””MAGNETIC “”” hematite beads instead. They fit inside the tubes.
I can place them into the tubes one by one until desirable motor speed is desired.
Need to purchase them now.

Can I ask where you buy your supplies? I'm buying some 100mm ring magnets to start with.

I buy a lot of my items from EBay. Stay away from China sellers now as you might have to wait a long time for a shipment to a arrive. Then you have to ask yourself is the shipment coated with the virus?
Look for the 45 degree aluminum angles on EBay.  Same for the 190 mm ring magnet and rod magnets
You can buy the Gorilla epoxy cheaper than buying it locally.  McMaster Carr has the polycarbonate tubes.

@Tom,

Your schematic is fine, but you uploaded a masked video. Can you supply us with an undoctored version of it working?

I plan within two weeks to show that video probably on the U Tube
On a table with transparent top or cement floor so no one can say there is something under it causing it to spin. And a side cover to show there is no compressed air stream blowing it around.
Also I plan to slow the speed down so one can see a definite rotation without the blurred image.

I am trying to understand what causes the rotation for the top ring magnet versus the fixed bottom ring magnet.

I understand the repel force between the block magnet and the rod magnet and also the strong attract force between
the top ring magnet and the rod magnet.  But all these magnets are placed onto the common platform which is supposed
to rotate together with the top ring magnet, right? 

You are right. The rod magnet is pulled downwards, and will remain there. I also can see no reason why it should move after reaching its end position, and much less i can see any reason why the whole rotor should rotate. There will be no movement at all. It's the same wrong reasoning as one year ago in the setup with the bar magnets inside the rotating drum. This time it's even more obvious that it can not work.

Early on I worked with magnetic systems such as the Wesley Gary device which was a good setup to get started on in my opinion. Over the years, as I progressed with my research I started seeing weird stuff going on and the reason why was seldom apparent. The problem is many times we see what we want to see versus what is present and occurring right in front of us.

For example we have a couple large but weak magnets which were all familiar with. Then under certain circumstances they start acting differently in certain setups and geometries for reasons we cannot understand. The problem here is that the magnet is polarized as a magnet but it can also be a conductor. Thus induced eddy currents from external fields can produce secondary magnetic fields within the magnet having almost any field orientation. It could oppose, it could assist or it could turn and break out entering other nearby magnetic materials. I have also measured field changes much faster than expected inducing currents as Wesley Gary claimed.

You see it can be something as simple as this yet if were not looking at it objectively with an open mind for what it is we could miss it. Is it a magnet or is it a conductor?... it can be both. This is also the most probable reason the inventors say only certain magnets having specific properties and geometries will work. The name Hans Coler also comes to mind where he physically wrapped his magnets with copper wire. Understand, these inventors did not generalize, they were very specific and meticulous in there work... details matter.

This might be the case in more complex (and dynamic) setups with active components. But this setup is completely passive. You are putting the magnets in place, nothing moves. Then you remove your hands from the setup, and what will happen ?  Will it start moving or rotating ?  I would say no. I can see no forces which would result in any movement whatsoever. To start any movement there should be some imbalance, and to continue the movement forever this imbalance would be required to persist forever. I don't see anything like this here.

That sound good Tom,  and may I ask you to slow down the rotor by your hand in that video and then let it accelerate again to its final speed?

One more thing:  have you tried to change the 45 degree angle of the plastic tube to have a higher or lower tilting angle?  Very likely it would also influence rotor RPM.  What do you think? 

Thanks, 
Gyula

I get a 1/2 turn spring recoil with two 45 degree ceramics and discs; Crude quick and dirty job. This kick reminds me of the spring action in my Kundel replication. There is definitely a very strong return to position force at work on the upper ring that responds to turning it!

I am puzzled by this point in place attraction (Cog Spot) over the bottom ring?

I brought the rod magnet onto the top side of the 45degree neo block in repel with a lot greater response.
Now the 45 degree block and angle go counterclockwise.

Thanks Magnetman,
I am going to try with 145mm as that seems to be the largest I can find on this site.
https://magnet.com.au/ferrite-ring-magnet-145mm-x-75mm-x-20mm.html

I will see if they have the other magnets I need as well, or close to.

Unless you can see any problems with changing the sizes slightly?
Do you think it needs to be aluminium, for the material used on the angles? Perhaps this is creating some sort of shield off balance and it needs to be aluminium to work?
I'm wondering if it will work with wood.  Can't wait to start diving in. I know a lot of people say this can never work but I have always believed there must be some way!
Eddy currents created from the first movement is probably what starts it, I doubt it would accelerate by itself from a stalled start but I could be wrong.

What would keep a builder from locking the top ring to an overhead gantry and allowing the lower ring to spin? This would bypass any imbalances in the setup. I have sourced a set of 5.3 inch rings and 1X2X.5  n45 neos. This is really a simple thing to knock out so decided to do it. I have 5 weeks off at the moment so why not. I will be setting the inside of whichever ring is to move with 3D printed pair that will have skate bearings in both sides. Thanks Magg for sharing as I need things to keep busy with. Love to play with magnets anyhow.
