Assignment: Field the Attraction Investigation
1. Iron filings were sprinkled on a poster board with just one magnet.
a. Describe the results. b. Use your knowledge of magnetic poles to explain the results you described. c. Use this illustration of a magnet to sketch a diagram showing some of the
magnetic field lines that occurred in this trial of the investigation. d. You made a diagram of the field lines on a sheet of paper. How do you think the
field lines would have looked if you had been able to do the same thing all
around the magnet, three-dimensionally? 2. Iron filings were sprinkled on a poster board with two magnets.
a. Use this illustration of two magnets to sketch a diagram showing some of the
magnetic field lines that occurred in this trial of the investigation. b. Use this illustration of two magnets to sketch a diagram showing some of the
magnetic field lines that occurred in this trial of the investigation. c. How are these two sketched diagrams similar? How are they different? 3. Name a metal, other than iron, that will work for this experiment (if filings could be made from
it). 4. Refer to this diagram of the magnetic field lines around Earth. How do the field lines for the
bar magnet compare to those for Earth?
