Detail Page

published by the NASA Marshall Space Flight Center
This NASA site describes long-term changes in Earth's magnetic field, and how magnetic stripes in the Atlantic seafloor provide evidence for reversals of this field.  The site presents a model of Earth's interior that helps explain how Earth's magnetic field is generated and how the reversals occur.  A computer-generated image shows the complicated magnetic field in-between reversals.
