Hay Jack,
Pretty cool. What you are collecting, I believe, is magnetite which if
often found in sandstone, out of which the beach sand was formed. It is a
naturally occuring product of nature. In the physics classroom we use iron
filings to show the magnetic field lines. I used to put magnets on an
overhead projector, put a piece of glass over them and sprinkle iron filings
on the glass. I never thought about photographing them. Now you have given
me some ideas.
I once asked a general science class what a bar magnet surrounded by iron
filings looked like to them. One student said it looked like a Hershey bar
someone left on the sidewalk that was attacked by ants.
