Lawrence Bragg begins the series with a brief survey of the history of magnetism and illustrates some of its familiar effects. A description of the fundamental properties of magnetic materials is followed by demonstrations with the lodestone, a modern magnet, and a magnetic compass. Magnetic attraction, repulsion and induction are next described and illustrated. Finally, Bragg discusses Faraday’s outstanding contribution to the subject, reconstructing many of his original experiments and supplementing these with demonstrations illustrating the effects of the magnetic field.
