Magnets and Magnetism

Today on Far Future Horizons we focus our attention on magnets and magnetism and the technological applications associated with this familiar yet mysterious force.

With their strange forces of attraction and repulsion, magnets are an endless source of fascination, and the familiar red and black horseshoe-shaped examples have long been fixtures in children's toy boxes. But the world of magnets goes far beyond kids' stuff. From electric guitars to deep-space exploration, Modern Marvels® takes a fascinating look at the pervasive and powerful magnet, showing how it serves to underpin a vast range of the devices and technologies that we take for granted in the modern world.

Experts like physics professor James Brooks and Jack Crow, the director of the National High Magnetic Field Laboratory, explain the principles behind the unique properties magnets, and details how they are used in TVs, vacuums, computers and telephones. From the refrigerator in your kitchen to the high tech refrigeration systems used in industry, we see how magnets shape the modern world and will continue to do so in the future.

Modern Marvels: Magnets is one exciting documentary that you will want to add to your DVD collection and is available from the History Channel’s online store.
