I could be watching Starsearch and be another productive citizen like you.
Science. RIP.[ Parent ]
It is sad to see so little interest in theoretical magnetic problems and so much rudeness here.[ Parent ]
We have all benefited immensely from the development of better magnets, but that is a field beyond the average persons capability. This is not the place for fundamental discussion on magnetic theory but I am sure there are such places on the internet.
One day if you make a better magnet then we shall all be grateful but I suspect that you will not be making a better windmill as the concept of unit poles doesn't work out too well and the homopolar generator remains in the land of one day wonders.

I appreciate your apology. Never the less I cannot see how theory and practice can be separated as one is a function of the other. It helps to know what you are doing but you do it.
Regarding a 'better magnet' or 'alternator', all I can say is watch the science news later this year and then repeat that statement.
What 'science news' you may ask. Well, you will know 'what news' when you see it.

It is based on the idea that if you cannot meet the 'master', then knowing his servants will tell much about him.
Magnetic flux is unique in that it is not corrupted by the act of perception as it operates outside time and lacks mass. It is a pure reference or datum plane.
If such a structure was possible it could unlock the secrets of gravity and also allow magnetic circuits that used induction (Eddy Currents) to increase not reduce output.
Hope this helps you understand why the construct interests me.
Best wishes,

From a practical standpoint when you try to bring the last few magnets onto the sphere they will insist on flipping. If you try to use some sort of machine to hold the magnets, the magnets will likely disintegrate as the individual magnetic domains flip causing strong stresses in the magnets. Just because you can conceive of something doesn't mean it can be built.GeoM[ Parent ]
The mechanical flip can be stopped, as I said. The internal magnetic 'flip' or demagnetizing is a function of the B and H curve of the material. For 55MGOe NdFeB the ratio is about 7:1 so if the imbalance exceeded this ratio the magnet would fail.
In the proposed design the magnetizing force and demagnetizing force is kept in limit by the pinned flux.
The greater the contamination of the super conducting material, the greater the pinning and 'draining' of one side of the circuit.
The device does not require the addition of energy for containment, like a Stellarator or Tokamak, as it is a relative field block not an external field bottle.[ Parent ]
