Interesting Magnet Fact:
A magnet is an object made of certain materials which create a magnetic
field. Every magnet has at least one north pole and one south pole. By
convention, we say that the magnetic field lines leave the North end of a
magnet and enter the South end of a magnet. This is an example of a magnetic
dipole ("di" means two, thus two poles). If you take a bar magnet
and break it into two pieces, each piece will again have a North pole and a
South pole. If you take one of those pieces and break it into two, each of
the smaller pieces will have a North pole and a South pole. No matter how
small the pieces of the magnet become, each piece will have a North pole and
a South pole. It has not been shown to be possible to end up with a single
North pole or a single South pole.
