HOW IT WORKS:
The two arm magnets have two points where the magnetic force is stronger. These places are called poles. The Earth acts like a magnet, too. It is as if there was a giant bar magnet in the center of the Earth, with two magnetic poles near the geographic north and south poles of the Earth. The red poles of the magnets are attracted by the Earth's magnetic pole, which is located near the north geographic pole. These red poles are called north poles because they point north. The blue poles are attracted to the Earth's south magnetic pole and are so called the south poles. The compass arm always rotates so that it points to the poles. Most compasses work like the Giant Magnetic Compass. The needle of the compass is magnetized at both ends and indicates the direction when attracted by the Earth's magnetic force.
