A science teaching material film from 1931 explains the principle of electromagnetism. When copper wire is wrapped around an iron rod and connected to a battery, it becomes an electromagnet. The film uses a fusion of live action and animation to demonstrate this fundamental concept.
Through this principle, the movie explores the structure and operation of electric bells and telephones. It shows how the same electromagnetic force that lifts iron can be harnessed to create sound and transmit voices over distances, making everyday communication possible.
