Question 1.
What do we observe when we sprinkle iron filings around a magnet?
Show hintHide hint
Think about the pattern they create.
Question 2.
What device can be used to demonstrate the magnetic field direction?
Show hintHide hint
Remember, a compass has a needle that points to north.
3Question 3.
What do iron filings demonstrate when scattered around a magnet?
- They remain random
- They align along magnetic lines
- They repel each other
Show hintHide hint
Consider the purpose of the experiment.
4Question 4.
True or False: The region around a magnet where its force can be detected is called a magnetic field.
- True
- False
Show hintHide hint
Recall how the force of the magnet operates.
Question 5.
If you were to change the position of the magnet and placed it off-center on the paper, how would you expect the pattern of iron filings to change?
Show hintHide hint
Consider how distance from the magnet affects strength.
Question 6.
Design an experiment using different types of magnets (e.g., strong, weak, horseshoe) to compare their magnetic field patterns using iron filings. What differences do you expect to observe?
Show hintHide hint
Think about how strength influences visualization.
