A quick question/thought for diamagnetic materials (or in particular
carbon).  I know you have been playing with carbon brushes, what about
carbon rods from a welding supply?  Usually they are covered with a
copper coat, but the copper peels off easily and a 3/16 dia piece I
played with is obviously diamagnetic.  The other carbon rod source is
the old fashioned dry cell =96 not alkaline =96 but carbon/zinc.  Pick yo=
ur
battery for the size rod you want.

The main question I had was, if you took several rods from a source such
as above, how about just laying them down, next to one another and hot
melt gluing them together, i.e., form a plate out of rods?  Would this
be sufficient for the diamagnetic plates?
