Peary's Compass
A compass is a device that indicates direction. It is one of the most important instruments for navigation. This compass was used by Robert Peary to reach the North Pole, allegedly the first person to do so.
Magnetic compasses consist of a magnetized needle that is allowed to rotate so it lines up with the Earth's magnetic field. The ends point to what are known as magnetic north and magnetic south.
As the needle would settle, the marked end would point toward magnetic north.
