In a magnet, identical magnetic poles repel each other and
opposite magnetic poles attract each other.

Earth’s magnetic field
The purple side with the
letter S corresponds to
the south pole of the
magnet because it will
always turn to face the
Earth’s South Pole.
The two-color rings (yellow and purple)
are actually magnets and so they have
magnetic poles. The yellow side with the
letter N corresponds to the north pole of
the magnet because if the magnet is
suspended by a very fine thread and is free
to rotate, the yellow part will always turn
toward Earth’s North Pole.
The region where
attraction or repulsion
takes place is called the
magnetic field.
