Earth's Magnetic Field interactive
This interactive animation lets you explore the magnetic
field surrounding Earth. Drag the compass through the space around Earth to explore the shape
of Earth's magnetic field. Many spacecraft have instruments called magnetometers that help scientists map
out the shape of planetary magnetic fields.
(Note: If you cannot see the animation below, or it is not working properly,
you may need to download the latest Flash
player.)
