View Resource About Electronic Magnetometers and Tobacco Smoking

This web page, authored and curated by David P. Stern, provides a non-mathematical introduction to modern magnetometers that depend on the saturation of magnetic materials. Applications include the observation the very weak magnetic fields in space and a 1979 experiment on the effects of cigarette smoking and the damage caused by asbestos. This is part of the site "The Great Magnet, the Earth"....

View Resource Electricity and Magnetism

Developed as a part of the Massachusetts Institute of Technology TEAL/Studio Physics Project, the Physics 8.02 Web site contains visualizations, course notes, and resources for MIT's Electricity and Magnetism course. The five visualization sections are: Vector Fields, Electrostatics, Magnetostatics, Faraday's Law, and Light. The course notes are organized by topic and have links to associated...

View Resource The Great Magnet, the Earth

This is a non-mathematical overview of magnetism and the Earth's magnetic field, written for the 400th anniversary of William Gilbert's book "De Magnete". It includes discussions of electromagnetism, solar magnetism, dynamo theory, ocean floor magnetization, and magnetospheres of Earth and planets. There is also a review of "A Millennium of Geomagnetism" and recommendations for teachers of this...

View Resource Dynamos, Magnetic Reversals and Plate Tectonics

These pages, authored and curated by David P. Stern, describe a dynamo process that creates the magnetic fields of the Earth and the Sun. Flows of electrically conducting material through existing magnetic fields produces electric currents, which maintain the magnetic field. Dynamos in the Earth's core reverse their north-south polarity, a process recorded by sea-floor magnetization, which...

View Resource Sun-Centered Physics

This site provides lesson plans that aim to teach pysics using the sun as an example. The lesson plans are called: 1. Position, velocity and acceleration; 2. Centripetal force and the law of universal gravitation; 3. Center of mass of the solar system; and 4. Introduction to magnetic spectrum.
