Magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star. It uses a magnetic needle that can turn freely so that it always points to the north pole of the Earth's magnetic field. Knowing where north is allows the other directions to be determined as well. Compass was widely used for navigation beginning in about the thirteenth century. ANTIQUE DESIGN:- The Antique Look Adds A Classic Feel That Never Goes Out Of Style.
