The Power of Magnets – 3rd Class Room 11

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.


  1. Outlined two racing tracks with marker
  2. Attached a paper clip to each car
  3. Two magnets were placed underneath the racing board
  4. ‘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.
