Discover the magnetic power of the Earth! Impress your friends with this huge compass, which has a width of 30 cm when constructed. It is ideal for scientific experiments at school!

OPERATION: The two magnets of the arm have two points where the magnetic force is stronger. These parts are called poles. The Earth also acts as a magnet. It is as if there was a giant bar magnet at the center of the Earth, with two magnetic poles near the Earth's geographic north and south pole. The red poles of the magnets are attracted to the magnetic pole of the Earth, 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 south magnetic pole of the Earth and are therefore called south poles. The arm of the compass always rotates to point 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 it is attracted by the magnetic force of the Earth. Instructions in Greek are included. Dimensions: 17 x 22 x 6 cm.
