This page, authored and curated by David P. Stern, and its annex describes, in trivial terms, the physics of magnetic fields and the history of its discovery. Included is the work of Halley, Oersted, Ampere and Maxwell....

This large NASA site presents the story of magnetic effects in near-Earth space. It describes Earth's magnetic field, its interaction with the stream of particles called the solar wind, Earth's radiation belts, and more....

This web page, authored and curated by David P. Stern, describes the causes of naturally occurring magnetite magnets, or 'lodestones.' It explains theories about the function of lightening and heat in such processes, and...

This material uses the Sun as an example of diverse parts of physics. Topics include weather and climate, magnetism and the interplanetary field, color, spectra and the electromagnetic spectrum, nuclear energy and its...
