The Chinese developed the first
compass as early as the 3rd century B.C.E. The first
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

lodestone will turn until it points in a north-south direction. -
