Andy,


1. Suspend a magnet from a string and use a second magnet to make it
move.
2. Place a magnet on a piece of cardboard and use a second magnet to make
it move.
3. Pick up some brads with a magnet then make an electromagnet with wire,
battery and nail and use it to pick up brads.


Note: Kids always pocket the magnets and other stuff.

Beyond Budget ideas that under the right circumstances they can watch you or
some volunteers perform but they cannot do all do individually:

1) Drop a magnet through a pipe (copper or aluminum).
2) Hang a magnet from a string and swing it over a metal sheet (copper or
aluminum).
3) Pump a magnet through a hanging coil of wire.
4) Move a wire through the poles of a horseshoe magnet and deflect a galvo.

Could try to ask a local magnet supplier for donations or scrounge supplies
from the machine shop scrap bin.

Let us know what you do.

Good Luck,
- JZ
