Introduction: Magnets have the ability to attract certain metals like iron and steel.
Metal paper clips are made from steel and should be attracted by a magnet but can a magnet attract a paper clip through a solid?
Hypothesis: Magnets can work through solid objects.
Materials: cardboard, plastic cars, magnets, paper clips, sign posts, markers.
- Outlined two racing tracks with marker
- Attached a paper clip to each car
- Two magnets were placed underneath the racing board
- ‘Start’ and ‘Finish’ flags were placed at either end of the racing board
Results: Racing board – the magnet had to work through a thicker piece of material but the magnet was also further from the paper clip which makes it harder for the magnet to attract it.
Conclusion: Yes, a magnet can work through solid objects.
