Subject: Spherical Magnets
Tappers, I just finished making what I think is a cool idea for the
3/4" spherical magnets.
I took a couple of feet of 1.5" ID acrylic tube and machined caps
for the ends. Then glued a 1/4" x 1.5 circle of Sorbathane to the caps.
Inside the tube I put a length of 1" x 1" x 1/8" Aluminum angle and
a Spherical magnet.
"Ta Da" I have a lens law tube that can be passed around, that the
students can see up close and personal.
More importantly the little beggers can't swipe the magnet, lose
the magnet, or worse get it covered with debris from the floor.
I post a photo Vacek's site. Zig
