| I am doing an experiment with
diamagnetic (repelled by magnets) materials and
magnets. I am trying to figure out what kind of
easily obtainable, diamagnetic material, is the
strongest (by levitation). The materials I am
using are: Pyrolitic Carbon, Bismuth, Lead,
Graphite, and Copper. I was wondering if you had
any of these materials (3x3 inches, 4x4 inches,
5x5 inches, etc., plates approximately 1 mm
thick) at UCSB or knew anywhere that might have
them (for a cheap price of course). I am looking
for 2 plates (all the same size) of each of the
materials. If you know anything, then please
me. Also, I was wondering if you guys have any
available mentors. I need a mentor also for my
Science Project so if you have anyone available
then please tell me. Thanks!|
I am not sure what you mean by "strongest"
respect to diamagnetic materials - I am assuming
you mean just "how strongly diamagnetic" they
Getting plates of the size you mention, let alone
at a cheap price, may well turn out to be a big
challenge. I don't know what your planned setup
is, but my sense is that your experiment will
require those plates to be very flat for reliable
results? That alone would be hard to achieve for
material such as lead or even copper (to get two
large plates to be the exact same distance
throughout their surface). Maybe you can do some
calculations to see what the effect of unevenness
of the plates or a variation in their spacing
their area would be, or try and come up with a
setup that requires smaller pieces of the
materials. The smaller, the better, most likely.
To get a hold of the kind of plates you are
thinking about, probably more by borrowing then
buying, you might want to try institutions that
give lectures or demonstrations of basic
whoever runs the beginning classes at UCSB or
college, or science museums. To buy them, maybe a
supplier of science equipment for schools and
universities is a starting point; maybe you could
check with your science teacher or look online?
You could call a place like that and see if they
can point you in a useful direction. Hope that
gives you at least some leads to pursue...
