| As you will see from these magnetic
experiments, magnetism (the invisible force) can
push and pull through some materials such as paper
and plastic.
Paper clips are made of steel. If
you hold a paper clip close to a magnet, you can
feel the magnet pulling on the paper clip with
an invisible force called magnetism.
All magnets have two ends or poles
(North & South). If you put the poles
of two magnets together, they will either pull
together or push apart.
They will pull (attract) each other
if the poles are different. They will push
(repel) each other if the poles are the same.
Experiments with
magnets will help you to find out more about the
way magnetism works and how it can be passed on
to some other objects.
Look for magnets
in old toys or on fridge stickers, or buy a bar
or horseshoe magnet from a toy shop.
