A magnet can push
things without touching it. A magnet can pull
things without touching it too. How does it do that? A magnet is a rock that has small pieces
in it. Magnetite
is a mineral
. This mineral pushes and pulls things near it. Magnets come in all
shapes. They can be many sizes.
How do magnets push or pull something without touching it? Magnets have a field. Think of a force field. Hold a magnet under a tray
filled with metal shavings
. You will see the magnetic field. The shavings will
be pushed away from the magnet. Move the magnet. The field will move too.
Every magnet has two magnetic poles
. One end is the north pole. The other end is
the south pole. The north pole of a magnet attracts (pulls) the south pole of another magnet. But the north poles of two magnets push
(repel) each other away. The push and pull is called a magnetic force
