Magnetism Field lines
Lay a sheet of drawing paper over a magnet of course you already know how to make a magnet and scatter iron filings on it. Tap the paper lightly, and a pattern forms.The filings form into curved lines and show the direction of the magnetic force. You can make the pattern permanent. Dip the paper into melted candle wax and let it cool. Scatter the iron filings on it. If you hold a hot iron over the paper after the formation of the magnetic lines, the field lines, the pattern will be fixed.
