perform such experiments as a hobby, for learning or as an art. This is how it
Start by placing a bar magnet or
any other type of magnet on a flat surface such as a table. Secure the magnet in

To keep the paper flat, place
small articles or balls of paper under the paper so that it will stay
Slowly and gradually sprinkle iron
filings on the paper. You may need to tap on the table or the paper so that the

(Warning: Hair sprays and spray paints are flammable. Do
your experiment away from fire and in a well ventilated area. Spray paint may
get to other areas of your work table. Cover such areas with newspaper if
Wait enough time until the spray
