Magnetic materials
Magnets can attract other magnets but they can also attract magnetic materials.
Magnetic materials are always metals but only a few metals are magnetic.
Iron IS magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip, for example, will be attracted to a magnet.
Most other metals, for example aluminium, copper and gold, are NOT magnetic. An aluminium drinks can, for example, will not be attracted to a magnet.
