Linked from

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

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

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

• 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.

• 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.

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

• 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.
