In 1820, a Dane by the name of Hans Christian Ørsted discovered the relationship between electricity and magnetism
Magnetism is a force that attracts and repels things. It is the result of the movement of charged particles. Although the theoretical concept may sound difficult, it is easy to demonstrate to even young children with very simple experiments.
Electrical engineer Rick Hoadley (a.k.a. Cool Magnet Man) shares his magnetic enthusiasm with this virtual textbook and dozens of experiments that you can either buy or build.
Exploratorium Snacks are not the kind you eat after school, but rather experiments you can do at home or in a classroom.
"Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits."
Walter H. G. Lewin received his Ph.D. in Nuclear Physics in 1965 from the Technical University of Delft, and has been an MIT physics professor since 1966.
Developed for science students in middle and high-school, this online textbook includes dozens of virtual experiments demonstrated with animated video, and discussion questions for classroom or home school.
