Asymmetric Magnetomotive Tugger (shortly: AMT)

[dieter]

Update: I have just observed an anomaly with diamagnetic graphite that makes this tugger much more plausible. You may repeat this experiment with only s pencil and a magnet. Yet to be verified tho. See here:

It is cool that you are doing such seemingly impractical investigations of tiny effects, because that tiny unnoticed things are only things left after centuries of massive investments into academies. In case of AMTs discussing here - I am interesting in changeless magnetic fields where distances between ferromagnetic and diamagnetic comonents are changeless and both vectors and magnitudes of magnetomotive forces are permanent. I tested many carbon based materials and found them acting similar to others diamagnetics and found that there great number of different compositions having vary diferent indices of magnetic susceptability varying from minus ten to minus hundreds for pyrolytic carbon.
Though interesting is your noticing that moving magnet producing multiple or complex effects - here I support your suggestion that also electrostatic forces could be manifesting along with weak magnetomechanical effects and carbon could form sort of domains capable to change its electic polarisation.
Plus... I've even seen videos where man has slab of carbon for levitation of strong magnet above that slab - what means that forces are sufficient to hover mass of magnet itself. Also, internet has many videos where tiny pyrocarbon plates hovering over sets of magnets.

That's right, pyrolytic graphite is often used for diamagnetic levitation.


Extreme diamagnetism has a diamond, at least in theory, like 10000, compared to 100 of Pyrolytic carbon, but when I tried it with a tiny diamond, it didn't perform more than graphite. I think it really is a diamond (uncut, 2mm cubus crystal) and no fake, as I was able to scratch a ruby with it.


Also very interesting in terms of diamagnetism: Nanotubes and Graphene...

Regarding mentioned here diamagnetic materials acting within magnetic flux:


1. it seams more practical - to analyze diamagnetics with application of lists or
tables of magnetic susceptibility (not permeability) where more negative indices
are associated with materials having properties of "stronger expulsion" of magnetic flux
and sort of repulsion of magnet itself;


2. it seams more practical to analyze magnetic flux as phenomena subscribed by
theories of  wave-particle duality where many manifestations allow to suggest that,
partially, flux behave similar to flows (of gas or liquids) manifesting behaviors
subscribed by formalizm of wave-mechanics such as refraction etc....
doing so you can contemplate that its more practical to experiment with thin plates
intersecting large portion of applied magnetic fields, - instead of application of same
bulk-mass of materials in shape of rods, cubes or balls - intersecting small part
of applied magnetic flux. Weight-to-surface ratios are important and can be somehow
interpolated with spread large but thin sails of a ship producing sufficient propulsion
while rolled-up sails cause that a ship is relatively motionless -
however mass of sails is the same.

I am observing a graphite pendulum, that hangs close to a microwave oven ring magnet. I push it slightly. It remains in motion for a extraordonary long time. However, as it swings closer to the ringmagnet, it often does not swing away again in the exact mirrored angle, but swings away in random angles +- 70 degrees of what is expected from plain action/reaction... very strange.


BTW. I agree with the surface vs fieldstrength thesis.
