hope this works
Hi,
Would you mind describing your setup a little ?? For me it is not self-explanatory, sorry.
On the upper left you have a magnet, indicate the poles please; is it a quarter piece circle magnet? If so it is hard to obtain?
Thanks

as the 'metal' gets attracted to the 'magnet' the arm rotates to the bigger end of the magnet then it flaps close (with the help of gravity) and the magnetic field is decreased while there is already another arm starting.

only thing is my design has a flapping mechanism to decrease the magnetic field.
Thanks for the hints.
The only thing I cannot get now is: Why your flapping mechanism is supposed to decrease the magnetic field when the non-magnetic arm closes ?? What material do you think of? Have you done tests with that material?
Because if that material really "absorbes" flux as if it were a flux "screener" and the metal sees less flux behind that material, then your idea has the possibility to operate as you planned.

the arm (can be anything non-magnetic) flaps close on top of the magnet, see i know you cant completly block the magnetic field, it just needs to be decreased to some extent.
the flapping arm can be real thick and light weight
no tests just ideas
Yes, ok but the main question is just the decrease of the flux to SOME extent, i.e. to an extent which is just enough to overcome the sticky spot at the top position. You would need diamagnetic material like bismuth or pyrolytic graphite sheets which are highly diamagnetic.
Found a link on bismuth: http://home.earthlink.net/~lenyr/levmag.htm and it seems to be formed easily at home to a flat sheet format too due to its low melting temperature point.
Also a good info on diamagnetic materials is here:
http://www.physics.ucla.edu/marty/diamag/ajp601.pdf and also here:
http://www.physics.ucla.edu/marty/diamag/diajap00.pdf
The "latest" strongly diamagnetic material is pyrolytic graphite and it is available just in the correct shape for your arm:

Now your idea can be tested! Go ahead!

thanks gyulasun
also when the arm flaps close there is kinetic energy that can be preserved in a circuit that can also help in turning off the magnetic field or at least decrease to some level. we would have to have seperate blocks of magnets in this case, have the last bigger magnet block turn off/on its field.
