Linked from

The 20 pages that link to Earth's magnetic field, each with the reason it gives.

• AuroraNarrower topic: It shapes the routes charged particles follow before they reach the upper atmosphere.

• EarthRelated: It deflects much of the solar wind and guides compass needles.

• Magnetic dipoleBroader topic: At large distances, its field is approximately that of a tilted magnetic dipole.

• GeophysicsRelated: Its variations probe the core and guide magnetic surveys of rocks and structures.

• Magnetic declinationNarrower topic: Its direction at a location defines magnetic north and therefore the local declination.

• Earth's coreRelated: Its changing strength and direction reveal the behavior of the deep core.

• HadeanRelated: Evidence for an early magnetic field bears on core activity during the eon.

• CompassRelated: The needle aligns with the field’s horizontal component.

• GeodynamoBroader topic: It is the observable field generated by Earth’s geodynamo.

• Inge LehmannRelated: The solid inner core she identified is part of the structure involved in explaining the geodynamo.

• Earth's outer coreRelated: Its long-term strength and variation constrain models of the outer core.

• Magnetic anomalyNarrower topic: Anomaly measurements are deviations from a model of this broader field.

• Earth's inner coreRelated: Heat and compositional changes associated with inner-core growth help power the geodynamo.

• Interplanetary magnetic fieldCompared with: Unlike the interplanetary field, it is generated by Earth and dominates the near-Earth region.

• Wilhelm Eduard WeberNarrower topic: Weber’s instruments and surveys helped make the global field measurable in standardized units.

• Internal structure of EarthRelated: The core’s physical state and circulation account for this field.

• Future of EarthRelated: Its evolution may affect atmospheric escape, though it does not prevent solar-driven climate change.

• Victor HessRelated: Later studies of cosmic rays used magnetic deflection to investigate their charged particles.

• Astrophysical electromagnetic fieldsBroader topic: It deflects much of the solar wind and shapes the magnetosphere.

• Geomagnetic poleNarrower topic: The geomagnetic poles are a simplified description of this global field.
