Throwing ideas around, mumetal and diamagnetic materials

[V-Spec]

i have attached a rough design.... very rough, been trying to visualize all of the forces in 3d which are present.

it shows a top down view of the 2 wheels with magnets, the gears to keep them aligned. The mumetal plate shield could be soft iron as well and the 2 half cone like diamagnetic materials, could also be pyrolitic carbon.

There is also a side drawing of the plate with the 2 half cones.

The point of this all being to totally cancel the repelling effect of the magnets on opposite sides of the rotors up until the critical point so they fly away creating motion.

The forces i see at work here are (and help me if im missing anything)

- The attraction of the magnets to the mumetal or iron plate (depends on the material and force and distance of the magnets)
- The diamagnetic repeling effect on the magnets countering the attraction and hopefully canceling it (depends on the thickness and type of material)

The magnets force on each rotor is negated because they're fixed to the rotor
The magnets force on the opposite magnet rotor is negated because of the size of the permeable shield.
i have set the rotor magnets to alternating poles but always repelling to promote the effect noted earlier in this thread.

ive seen youtube videos of neo magnets suspended between diamagnetic materials so im hoping the thickness of the diamagnetic material can make this idea feasible.

There is maths involved in all of the forces mentioned and i cant see why this will not spin if all forces leading up to the critical point are canceled / neutralised

Im looking for someone to seriously assist me with the mathematics part of it put some numbers together for me and will provide a modest monetary donation in advance.

Thickness of permeable metal, strength and distance of magnets and most importantly thickness of diamagnetic semi cones.

i know its a long shot because in fields like this the math usually doesn't fit. But all effects are hopefully known and can be calculated. I want to make this happen.

Remember trying various shields a few years back on this idea.

Never did update the page, but remember trying different shields, static and on the rotor.

The effect you show in the video seems to work just as well on regular metal as well as mumetal.

Yes, it's a property of ferromagnetic materials and isn't limited to mumetal.  The important thing to remember is the metal must be thick enough or have a high enough permeability to hold the flux.  Also, if the metal is too thin to divert all the flux, then you can try weaker magnets or possibly increasing the distance. If the metal is over-saturated, then the shielding effect will decrease due to flux leakage.

im worried that the diamagnetic material will have to be too thick for this to work

anyone with experience melting and using bismuth and pyrolitic graphite in shielding / canceling application.

any mathematicians, i suspect most i talk to will automatically dismiss what im doing. to hell with them, just do my maths!

If you get the right ratio on the shield will it will cancel the rotor magnets attraction to the mumetal while shielding it from the opposite rotor magnet until it repels when it moves away from the shield.

The magnetic flux is conservative. Whatever the environment (mu-metal or air) the field lines loop and there is always the same number of lines i.e the same flux which is thus balanced when the magnets are approaching or when they move away.
A magnetic field is never "shielded". It is deflected. The field lines are never broken, they follow the so-called "shield", for example a piece of mu-metal.
In other words the field gradient in which a magnet "falls" is the same as the field gradient from which the magnet have to escape. As the work done to move in a potential gradient from A to B is path independent, it is the same, sign except, as to move from B to A. The energy is balanced, there is no gain. I guess that in your particular setup, the equilibrium position in which your motor will hang up, is when two opposing magnets are near and a bit beyond the end of the mu-metal "shield": at this position, the back force of attraction by the mu-metal will be dominant and will cancel the repulsive force of the magnets ahead and the forward attracting force of the magnets behind.
We always see the same error of reasoning again and again in each pmm. There is not one differing from another. To use paramagnetic materials doesn't change any thing.
