Magnetic
ducks
Make two ducks
from paper doubled over and glued and push a magnetised pin into each one.
Place the ducks on cork disks in a dish of water. After moving around they line
up with their beaks or tail tips together in a north-south direction. The ducks
approach each other along the magnetic field lines. Their movement is caused by
different forces: the attraction of unlike magnetic poles, the repelling effect
of like poles, and the earth’s magnetism. Set the magnets so that two poles
which will be attracted are placed in the beaks.
