Question 4
In groups, find the magnetic field between two magnets.
1. Collect two magnets, a piece of paper, some iron filings and a transparent plastic bag.
2. Place the magnets inside the bag.
3. Place the magnets on a flat surface with like poles facing each other.
4. Rest the piece of paper on top of the magnets.
5. Pour some iron filings on the piece of paper.
6. Gently tap the piece of paper until the iron filings are spread out in a pattern.
7. Repeat the process with opposite poles facing each other.
8. Explore the magnetic field all around your two magnets. Start with the arrangements shown in Figure 11.9. Then try some more of your own.
Draw the magnetic fields on a piece of paper and compare them with your classmates’.
