The Story Of Magnetism (1960)

Discusses the concept of magnetism, its historical discovery, and its applications. It begins with the introduction of magnetite, a rock that attracts iron, and the development of the compass by mariners. Dr. William Gilbert’s studies in the 16th century revealed that magnets have poles that attract and repel, and he demonstrated that the Earth acts like a giant magnet. The text explains how magnets create magnetic fields, the properties of permanent magnets, and the relationship between electricity and magnetism, including the creation of electromagnets and generators. It concludes by mentioning ongoing research into the nature of magnetism at the atomic level.
