The Wonders of Magnetism1915

  • 3.5
A science film meant for educational use. These carefully staged and often elaborate classroom demonstrations subtly remind us of Edison's own technological achievements. As Moving Picture World remarked, "An educational film which is full of interest, illustrating the two kinds of magnets in common use, the electro and the steel magnet, as an aid to science and industry." The electromagnet is shown to be far more powerful, and the principles of electromagnetic iron ore separation are demonstrated. In fact, Edison had lost much of his fortune through disastrous investments in his large-scale iron ore works. (W.K.L. Dickson had worked alternately on iron-ore separation and the development of Edison's motion picture system in the early 1890s.)

Worth watching. Says as much about human nature as magnetism. The demonstrators in this clip are having just as much fun as present-day kids messing around with fridge magnets and paper clips. There's something about magnetism that retains mystery and defies everyday understanding, even though we've had knowledge of - and worked with - this force for generations.

Fun in science/physics lab, in the early days!
