Magnetic wheel by steel shielding

[norman6538]

The problem with metal between 2 magnets is you have 2 sticky spots on each side of the metal and worse yet they are closer than the magnets are so the sticky is more than doubled because they are closer. Been there done that many times.

Due to COVID and winter weather I have been working on the Flynn parallel path ideas. You can take two long strips of metal and slide a magnet between them but not touching them and move the flux from one end to the other. For max power the gap needs to be very small ie. .008 in. ie postcard gap. That is hard to embody quick and dirty.

And I am also working on an enhancement to this Flynn idea combining a Butch lafonte  trick. I'll get back when I have measurements to share.

But I did not find that sliding another mag down close the one already there as Flynn proposed - makes any additive or multiplicative attraction force.

That was very discouraging plus after all these years we have not heard of any Flynn motors.

Vineet, this ceramic blocks the field without being attracted or repelled by it, inventor does not reply to emails and you cannot buy it.

Second video shows  that magnet is getting repelled. Few comments say that it is bismuth which is a diamagnetic material.

A ferromagnetic material is attracted to both N and S poles and a diamagnetic material is repelled by both poles.  If a alloy of  ferromagnetic  and diamagnetic material is made with suitable percentages,  the attractive force on one material is neutralized by  repulsive force on another material hence we may get a shield which is neither attracted nor repelled by magnet.  It may block field from very weak magnets because repulsive force experienced by a diamagnetic material is very less compared to attractive force on ferromagnetic material.

If somebody has strips of both ferro and diamagnetic material, he can try making a 'forceless'  shield by sandwiching two strips with different thicknesses so that attractive force is balanced by repulsive force.

Magnet is repelled from other magnet when ceramic is lifted, there is no repulsion from a ceramic at all.

Bismuth is most diamagnetic (which is way too weak anyway) but what we see is not repulsion, it is neither a Meissner effect. Those in the comments are just mis-guessing.

Apparently this ceramic absorbs magnetic field as if it were a black hole while not being attracted or repelled by it.

The video as evidence, seems to indicate that the shielding material has a
fair to good degree of effectiveness.

Since we do not know the composition of the shielding material, we cannot
replicate  the demonstration.

The shield material appears to be cast. It has some bubbles.  It may be a ceramic
or it may be a plastic, perhaps epoxy matrix, in which is contained some combination
of materials which create a diamagnetic effect.

What ever its composition, and what ever its effectiveness, we do not definitively know.

which create a diamagnetic effect

Again, this has nothing to do with diamagnetic effect. There is no repulsion here. Magnetic field just disappears in the material without any perceptible interaction.
