A physics / Stamp related question
Hello,
I am trying to find a liquid material that can be
controlled (moved) via magnetic attraction. I know
this is a bit of an unusual question. I'm an artist
and I'm trying to incorporate the Stamp into my
artwork, I'll be more than happy to elaborate to
anyone that is interested. I assumed mercury may be a
liquid that can be moved via a magnet, however, I
don't think it's that safe of mediums to be working
with. Have any ideas?
Thanks, in advance, for your creative input! [noparse]:)[/noparse]
Best of Regards,
Todd

film Liquid Crystal technologists may help. How about using very, very small
diameter ball bearings or even iron filings (remember the magnet experiments
in school?) in a shallow plastic dish suspended in a low viscosity liquid
and pulsed electro-magnetically?

and that would be worse than mercury. Sure would be pretty though.
Perhaps you could suspend very small metal shavings in an extremely viscous
fluid. The only thing that comes to mind is the mud that is used when
drilling for oil.
Hope that helps.

source than Ed Sci is a manufacturer called Ferrofluidics. They have a wide
selection of different solvents containing micron-sized iron filings with
different magnetic susceptibilities (strengths). I've used ferrofluid in
mineral oil for various purposes. When a small drop is put in water, is
forms a black bubble. When a magnetic field is in the vicinity, the iron
particles line up along the field lines and the bubble is attracted toward
the magnet, acting like a liquid paramagnet.
Contact me off list for Ferrofluidics phone/address, and I'll dig it out of
my files.

What you are looking for is called ferro fluid. Try Edmund Scientific (
www.edmundscientifice.com ) and look at item number CR82-215 (
http://www.edmundscientific.com/Products/DisplayProduct.cfm?productid=2577 )
and CR82-216 (

Ferrofluid should be readily available in small quantities from speaker
repair shops. It's commonly used to fill the magnetic gap in tweeters, to
improve heat dissipation and damping.

I understand there is an article on Homemade ferrofluid in the
Journal of Chemical Education July 1999 v76 page 943. I do not have
the article yet, but hope to within the week.

Todd,
There are only three materials that a magnet will
interact with. Nickel, Iron and Cobalt or
alloys containing some combination of the three.
I'm not a chemist so I can't tell you how to keep
these elements in a suspension that doesn't
separate. I think that would be your major problem.
Powered iron in water or oil may work for you, add
food coloring or dyes for color.
Industrial mechanical feedthroughs for vacuum chambers
use Ferro-Fluidic feedthroughs where the gap between
a magnetic shaft in a bearing is filled with a magnetic
suspension allowing the shaft to rotate freely with no
leaks. You might be able to get a magnetic suspension
from one of these feedthrough vendors such as MDC, ect.
Good Luck,
Greg
iron particles, each coated with a substance that keeps them separated.
Brownian motion disperses them with random magnetic orientation in the
absence of an external magnetic field.
