What are magnets made out of?
For some materials, the molecules are magnetic. Usually, these molecules
are all scrambled up, so you do not know they are magnetic. Sometimes they
can be lined up. When this happens, you have a magnet. Metals like iron
and steel are good at lining up their molecules. Some plastics, like the
ones you see on refrigerators, are good at lining up as well. The molecules
of most materials will not stay lined up. They just get all scrambled
again. This is why most materials do not make good magnets.
