The Astronomy Center has provided educational resources to introductory astronomy educators since 2003. Over the past 20 years, the rapid pace of discovery has rendered some of our linked resources obsolete. Thus, the Astronomy Center will be decommissioned on March 1, 2022. Our highest quality resources will be retained on ComPADRE.org.
This set of five web pages provides a non-mathematical introduction to the motion of charged particles in magnetic fields. These pages describe the "guiding center motion" which determines the motion of ions and electrons trapped in the Earth's magnetic field and in laboratory plasma devices. Also covered are gyration and mirroring, adiabatic invariance and drifts due to an electric field and gradients in the magnetic field intensity. This is part of the work "The Exploration of the Earth's Magnetosphere". A Spanish translation is available.
