When was the Magnetic Compass Invented?
The magnetic
compass always points towards north. The earliest one was
first used
by the Chinese in about 1000 A.D. and came to be used in Europe about 100 years later. The
first compass was a
magnetized iron
needle placed on a piece of cork or straw floating in a
dish of water. The Chinese, in about 100 BC, discovered that
if spoons made of the magnetic mineral lodestone were
spun, they came to rest with the handles pointing in
the same direction. The reason was because the Earth's magnetic
field acted on the spoons like a compass. The compass later
developed from
this observation. The compass we use today was invented in
1200s. It
consists of a pivoted
magnetic needle on a card with directions.
