The prismatic compass indicates the positions of objects in relation to the Magnetic North. The Magnetic North is the direction that a compass needle points towards due to the Earth's magnetic field. The prismatic compass is a navigation instrument that uses a magnetized needle to indicate Magnetic North, which can then be used to determine the direction of other objects or locations. While the Earth's True North is the direction towards the geographic North Pole, and Grid North is the direction towards the top of a map grid, the prismatic compass specifically indicates Magnetic North.
