Induced magnetic field to overcome sticky spots

[gyulasun]

Hi Onevoice,

I attached a modified picture of your Picture18.jpg to indicate how big cut-out I think would be better than your present small hole to reveal any one magnet at a time.  Maybe you would think my suggestion is a too big cut-out...  but the hole in your picture shown seems to me too small and that explains the small flux density.
Another factor to consider is the distance between the magnets and the plate,  I think what you show in Picture17.jpg is a bit big distance but this surely depends on the strength of the magnets and also the size of the cut-out. I understand that too small distance is also to be avoided because the mechanical strength of the shielding plate sets up a limit on that (it can simply get deformed by the strong attract forces when magnets are just leaving or coming to the cut-out edges of the plate).
I do not think you violate the Steorn patent, for they have magnets in one row next to each other above and around which the shielding plate moves and their magnets are not with changing poles like in your setup. Do not bother about this.
