Video Description:
Suspended steel filaments make three-dimensional magnetic fields visible. See http://amasci.com/electrom/statbotl.html
I came up with this one for the Electronics exhibit at Museum of Science, but it ended up as a build-it device for science teachers.
I also discovered that baby oil slowly pushes its way through glued plexiglas joints. If you build an 8" cube of thick plexiglas and fill it with baby oil, a few months later you notice that it's half empty! And the other half is soaked into all the books on the shelf below! AND IT'S A SHELF IN A COLLEAGUE'S OFFICE!!! :)

It's not fibers. You could try and see what happens though.
Manual focus only works at 50cm. For close shots I have to use macro with autofocus which cannot be disabled. Cheap $200 camera!
Low-viscosity oil, easy to shake up after iron has settled out. Flat plastic bottle for free!
Make a "C-shaped" magnet with the fields very close together. All the field will be in the gap between the poles.
