V Gate Magnetic Config

  I am looking at using bismuth as shielding although alkaline is a cheaper alternative but not as effective.  Dimagnetics basicly act like a mirror to magnetic forces, the forces cannot penetrate the surface and are reflected back.

Hi,

If you look for the magnetic permeability of bismuth, you will find it 0.99983  so just a tiny bit less than 1 which is the chosen permeability of air (for comparison).  So it is simply not true that the forces (I suppose you mean flux lines here) cannot penetrate the surface.  And if you were to use a rather thick piece of bismuth, it would be almost equivalent to the effect of an air gap corresponding to the thickness of the bismuth.

I don't want to discourage your experimenting and development at all. However, I don't believe that bismuth will do what you need. Take a look at this link from back in 2009/2010: http://www.overunity.com/8472/magnet-shielding/msg236766/#msg236766


Good luck with your discoveries and hope you keep posting

Hmmmm, Was looking at bismuth in my original design, to use as a cap over the magnets. like a quadrant of a sphere.  allowing the attraction and then repelling once the magnet had passed over the bismuth.  Thankfully that was an old design idea and bismuth isn't mission critical in this design!!!  Thanks for the heads up on bismuth

@Jdneilson:


Is the attached non-3d image sort of what you see for your V-Gate design?
