Emily,
I had the same problem. My solution was to purchase two large neodymium magnets and place them inside of 2 "PVC pipe fittings that mimic the shape of those radar magnets. The base of each of the PVC pieces was bolted to a mounting plate through a kitty litter pan. The pan is set recessed into a table. This has held up well for several years of heavy use. Several years ago, someone here suggested a steel sand blasting grit commercially available and we've replaced the black sand with that material.
Hope this helps,

I have acquired some black sand/magnetite and was trying to replicate an exhibit like the one at the Exploratorium on Black Sand. http://exs.exploratorium.edu/exhibits/black-sand/

Something eye catching, or if anyone knows where to purchase a radar magnet please let me know. If you have any other ideas for a Black Sand exhibit I would love to hear them. Thank you
