We played with them as children, but the world of magnets isn't kid's stuff! The pervasive magnet serves as the underpinning for much of modern technology. They can be found in computers, cars, phones, VCRs, TVs, vacuum cleaners, the washer and dryer... (more), the ubiquitous refrigerator magnet, and even in an electric guitar! On the cutting edge of technology, scientists experiment with a variety of magnets. Magnets' amazing forces of attraction and repulsion may some day take us to the far reaches of outer space.
