It typically consists of a magnetized needle or another element, such as a compass card or compass rose, that pivots to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers.

The luopan or geomantic compass is a Chinese magnetic compass, also known as a feng shui compass. It is used by a feng shui practitioner to determine the precise direction of a structure, place or item. Luo Pan contains a lot of information and formulas regarding its functions. The needle points towards the south magnetic pole.
