Suspended steel filaments make three-dimensional magnetic fields visible. See http://amasci.com/electrom/sta... 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!!! :)

i see you have a good size electric motor in the back ground that is unwound. can u make a video of how to wind them, i can never get it to work

Water will make the steal rust, I could be wrong, but it seems logical.

Ah ok! Thanks.

> confine the magnetic fields on one spot?Make a "C-shaped" magnet with the fields very close together. All the field will be in the gap between the poles.
