If you are given some iron fillings and a magnet describe how you would find the poles of the magnet?
If possible cover the magnet with a sheet of paper and gently sprinkle the iron filings over the sheet ot paper, they will stick in a pattern following the magnetic "lines of flux" which will get closer and closer near the poles of the magnet. Afterwards you can cleanup by lifting the sheet of paper off of the magnet and the filings will fall away. Without the paper the filings will usually become tightly stuck to the magnet, making it hard to clean.
