4. For each of the materials, put one layer of the material between the magnet and the detector. Test tor the presence of a magnetic force in two ways. Record your observations in the following chart.
5. Repeat step 4 but put 4 layers of each material between the magnet and detector. Record your observations in the chart.
6. Repeat step 4 but put 16 layers of each material between the magnet and detector. Record your observations in the chart.
