Magnets

"From electric guitars to deep-space exploration, this documentary 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 Filed Laboratory, explain the principles behind magnets' unique properties, and detail how they are used in TVs, vacuums, computers and telephones."
