Modern devices for measuring this phenomenon rely on proton precession, and noted anomalies in it have been detected in Mongolia and the South Atlantic.

Both the ring current and ionospheric dynamo contribute to this phenomenon that was first measured by Gauss in 1835. The zebra-striped pattern of the ocean floor records past reversals of this entity that interacts with the solar wind to create auroras. The rotation of the liquid outer core contributes to what phenomenon that causes a compass needle to align with the poles?
