The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.

We now believe that terrestrial magnetism is the result of processes within a liquid, iron-rich layer of the earth's outer core.
;the science which has for its province the study of the magnetic phenomena of the earth. Its early growth was slow, and considerable uncertainty prevails as to its earliest developments.
Orders of magnitude are derived for a number of quantities connected with the dynamo theory of terrestrial magnetism. It is concluded that the dynamo theory does provide a self-consistent account of the origin of the earth's magnetic field and raises no insuperable diffi- culties in other directions.

Department of terrestrial magnetism (dtm) archived since: jul, 2018. Description: this collection documents and preserves websites maintained by the carnegie institution's department of terrestrial magnetism. In 2020, the department of terrestrial magnetism merged with the geophysical laboratory to form the earth and planets laboratory.
Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind. This is a stream of charged particles leaving the sun's corona and accelerating to a speed of 200 to 1000 kilometres per second. They carry with them a magnetic field, the interplanetary magnetic field (imf).
When the winding gets extreme, the magnetic field lines snap, causing solar flares at those locations on the surface.

Within the equator’s neighborhood, however, the results by the device are enough in agreement with the facts and show well that the irregularity in terrestrial magnetism’s distribution is due, at least partially to the magnetizing effect of the seas. This effect is confirmed by the fact that when duplicating thickness with hard cardboard plates at the zones of large depth in the oceans, the results are diminished.
