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 pieces of magnetite
in it. Magnetite
is a mineral
. This mineral pushes and pulls things near it. Magnets have many shapes. They have many sizes.
How do magnets push or pull things? 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 attracts (pulls) the south pole of another magnet. But two north poles push (repel) each other away. The push and pull is a magnetic force
