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 site from the Goddard Space Flight Center presents hourly "'Near-Earth' solar wind magnetic field and plasma data, energetic proton fluxes (>1 to >60 MeV), and geomagnetic and solar activity indices." In addition...

Originally conceived and launched by consultant and Senior Research Associate Dr. Timothy E. Eastman at the Space Science Institute in Boulder, Colorado, the Perspectives on Plasma Web site represents all aspects of...

This inquiry-based lesson plan is intended to be used in tandem with the PhET Electric Field Hockey simulation. Students place electric charges on a simulated ice field to guide a hockey puck into a goal. As they...

The teaching of physics is clearly enhanced by the use of demonstrations. Visual examples of abstract concepts aid immeasurably in their mastery. They also provide an opportunity to illustrate the scientific method and...
