Title: Earth's Inconstant Magnetic Field
Url: https://science.nasa.gov/science-news/science-at-nasa/2003/29dec_magne...
Publisher: United States. National Aeronautics and Space Administration
Description: This National Aeronautics and Space Administration 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.
