Description: Uses a simple electromagnet and a small hand generator to demonstrate that electricity and magnetism are interrelated, that an electric current can produce magnetic effects, and that magnets or magnetic fields can produce electric current. Includes views of the generators in the powerhouse at Hoover Dam, showing that they work on the same basic principle as the hand generator, but that they produce enough electirc current to light a city. Collaborator, Albert V. Baez., Shows that electricity and magnetism are closely related. Shows relationship of electricity and magnetism. Demonstrates how electromagnets are made and used.
