They fill the space around a magnet where the magnetic forces work, where they can attract or repel magnetic materials. It would be difficult to draw the results from the sort of experiment seen in the photograph, so we draw simple magnetic field lines instead.
This activity was developed by NOVA as a Student Activity to accompany the NOVA movie Magnetic Storm. Understand that the Earth’s magnetic field not only changes magnitude, but also direction over time. During this activity, students will use a hand-made magnetometer to identify and describe positions of strong magnetic field on models of the Sun. The TXESS Revolution is funded by the NSF Opportunities for Enhancing Diversity in the Geosciences program under NSF Grant 0703687, the Shell Oil Company through a grant to the Texas Regional Collaboratives for Excellence in Science and Mathematics Education, and the Jackson School of Geosciences at UT Austin. Magnetic Field The region in which the magnetic forces created by a permanent magnet or by a current-carrying conductor or coil can be detected.

MESSENGER also found that the magnetic field is offset toward the north pole by about 20% of Mercury's radius. We will use the procedure described in the National Center for Atmospheric Research Climate Discovery Teacher’s Guide on Magnetic Sun. Any opinions, findings, and conclusions or recommendations expressed on this Web site or found in the materials provided are those of the TXESS Revolution investigators and do not necessarily reflect the views of our sponsors, including the National Science Foundation. The axis of the magnetic field is tilted with respect to the Earth's rotation axis by 11.5A°. This happens when stressed or flexing magnetic field lines about a third of the way to the Moon squeeze together and reconnect.
Recent infrared imaging of Venus' surface by the Venus Express spacecraft shows material that has just come out of some shield volcanoes, so Venus is still active.
Charged particles in Jupiter's radiation belts that are energized by the solar wind spiral around magnetic field lines to produce electromagnetic radiation in many different frequency bands. That sends a massive burst toward the Earth that hits the upper atmosphere to make the aurora eruption.

In addition, there is a flux tube of electrical current of millions of amps flowing between Jupiter and its very geologically-active moon, Io. As an introduction to exploring Earth’s magnetic field, we will do a short activity on Visualizing Magnetic Fields using the NOVA worksheets.
As described in the Jupiter moons section, Io has a number of volcanoes erupting all of the time. Particles in Jupiter's radiation belts collide with the volcanic dust particles and charge them, further adding to the radiation belts.
