YOU WILL NEED
→ all the magnets
→ box with iron powder
HERE'S HOW
1. Place the box with iron powder on top of
each of the magnets in turn, as you did
in Experiment 19.
2. This time, though, pay special attention
to the patterns that form after shaking
and knocking the box holding the iron
powder. Keep the magnet pressed
tightly against the box as you do this.
You may have to try it a few times before
you get a pretty pattern.
