Exploration and travel compass
Chinese compasses were pieces of a magnetic mineral
called lodestone. Earth itself is like a giant magnet with
north and south poles. Because lodestone is magnetic, it is
influenced by Earth’s magnetic poles. If you put a piece of
lodestone on wood and float it in a bowl of water, the
lodestone will turn until it points in a north-south direction. -
