Still image from Electromagnetism

Part of the "A 3-D Demonstration" series. Traces the relationship between magnetism and electricity from the first accidental discovery of induced current. Introduces the concepts of electric and magnetic fields and explores their representation. Examines the features of coils and solenoids to develop the construction of practical electromechanical devices, such as solenoid switches and electromagnets. Also introduces hand rules to help determine the alignment of currents and fields. Specific modules include Electric Fields, Magnetism, Magnetic Fields, Electromagnetism, Left-Hand Rule, Electric Coils, Solenoids, Solenoid Switches, and Electromagnets. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act). Accessibility options on the DVD are: (1) expanded description, (2) English subtitles in a black box, (3) subtitled description.
