LINES OF FORCES

Stuff you need

1. A sheet of paper
2. A magnet
3. Steel filings (these can be made by taking a steel wool pad and pulling it apart until you get a small pile of tiny pieces of steel)

How to do

1. Set the magnet on the table
2. Cover the magnet with a piece of paper
3. Sprinkle the steel filings over the paper

Result

1. The filings will take the shape of a "figure eight ", which is the lines of force of the magnetic field

Why

1. The filings will line up along the lines of magnetic force which are close together at the poles of the magnet and farther apart as you move away from the poles.

Extra stuff to do

1. Use different sizes and shapes of magnets
2. Use different textures of paper
