1. Draw and describe the following: When two magnets have north and south sides
toward each other what happens? Why? (label: poles and magnetic field)
2. Draw and describe the following: When two magnets have the same poles
(north/north or south/south) toward each other what happens? Why? (label: poles
and magnetic field)
3. Draw the magnetic field of one bar
magnet.
Draw the magnetic field of filings
that were blown with air.
Predict which magnetic field above most closely resembles that of the Earth’s.

4. Prediction: Draw and describe your predicted method for making a magnet with a
nail, copper wire, and a battery. Why do you think this will create a battery?
5. Method Development: Draw each method that you used to try to make a magnet
and describe the results of each trial. Why do you think it did or did not work?

6. What was required to make the nail magnetic? Is this a permanent magnet or a
temporary magnet?
7. What do you think is happening to the nail to make it magnetic?

8. What can you conclude about the relationship between electricity and magnetism?
9. What analogy can you make between the magnet you created and the Earth’s
magnetic field? In other words, draw connections between features of your magnet
and the features of the Earth’s magnetic field.
10. How does the magnetic field protect Earth?
