Description: Points out the relationship between electricity and magnetism and shows how this relationship is used in the design of electric motors and generators. Defines electric current, demonstrates how a magnetic field exerts force on an adjacent magnetic field, and explains the principle of the electric generator. Reiterates that electrons in motion are always surrounded by magnetic fields and that magnetic fields in motion always force free electrons to move., Magnetism and Electricity From the series General Science Film Series Produced by McGraw-Hill Films; 674 Via De La Valle PO Box 641; Del Mar; CA; 92014PC: MGHT Year published 1965 Grade Level: I J H Distributed on media: 1 film reel (17 min.), optical sound, 16 mm.
