Self powering PMM Motor

Here I described the same effect, in this implementation the entire flux may disappear into the strip while it's shorting-out the magnet.

COUNTER ROTATING FIELDS
ABSTRACT
Delayed magnetomecanical entrainment utilising 3 point interaction[1] by means of inductive shielding[2].

This way there is either north or south coming though never both, it works like a filter. Now you can turn the magnet on and off like a switch. lol

Just a half baked idea.  I can not verify this since I do not know how to run femm yet.

This is a take off of the Cheniere ppt file. In an attempt to make an unbalanced magnet left to right.

Attached is the slide 3 of the ppt file and a crude drawing I put together.

The thought is to place a very thin piece of material on the side of the magnet that will absorb only SOME of the flux on the one side.  This would need to be something that saturates completely quickly so it doesn't take too much.

If someone could do a quick simm of this, it would be interesting to see.

Sorry for being an armchair participant.

The document you're refering to has an idea how to actually move one field line from leftside to right side so the total number of magnetic lines are not equal on both sides. However, the iron part will in fact move more magnetic lines to that side you put the iron, but as soon as another magnet is approaching, its magnetic fields also want a piece of that iron, and the forces are again symetrical. I am calculating some other ideas how to "trick" the magnets, so stay put.

But if the iron is already saturated with the magnetic lines from the magnet it is attached to, it should not be able to influence other magnets. (Most likely, I am showing my lack of magnetic knowledge here)

Hi Nutcracker.

It takes a lot more flux than you think to saturate iron.
First of all you must make sure that all flux lines are passing through the iron.
In the setup you suggest the iron is far from getting saturated.

I have attached a picture of two saturated iron pieces. Well, at least as good saturation as a NdFeb can provide at their 1.5T.
You should have in mind that iron saturates at 2.15T and this flux level is a lot higher than the strongest NdFeb can provide.

Hello Nutcracker,
this is also my opinion.
I've tried a basic experiment with one magnet shielded (stationary) at one side (Metaglas) and another opposing magnet nearing from beside:
The center (lock in) is shifted from the middleaxe of the stationary magnet to the shielded side, but the unshielded side stays active as before (radius of action).
There is a shielding (shaping) effect on the shielded side, but the distribution of the resulting forcevectors is unclear yet.
The target is to avoid a forcevector, which points in the area of greatest work to the middle (datum) of our disk shaped rotor because this force would be lost in the axles bearings as heat or pressure but not as wanted in torque.
If booth magnets are shielded the centerpoint (lock in ) moves far more above the middleaxle and the resting situation is like drawing a new centerline through the volume of the iron/magnet-body.
The forcedistribution while moving booth structures against each others is verry different from unshaped to shaped magnets.
Best wishes

In a saturated iron part, there is no room for more magnetism. However, the magnetic lines which is not going through the iron part, will in sum just move the total magnet to another virtual magnet placed somewhere in that direction. The sum is still just an ordinary magnet, but weaker. So the weakness counts up for the desired properties, and cancels therefor out what you win.
