You’ll find magnets everywhere in our modern world. From the humble refrigerator magnet to the Hubble Space Telescope, magnets impact almost every aspect of our lives.

You’ll find magnets in many everyday electronic devices. If an appliance has a motor in it, you’ll find a magnet. Televisions, computers, automobiles, loud speakers, cell phones, and microwave ovens, all use magnets. Magnets are used to keep kitchen cabinet doors closed, are part of the sensors in home alarm systems, are placed in cows stomachs to catch barbed wire and nails, are used in magnetic resonance imaging systems, are used to slow elevators, roller coasters and subways, and in countless other devices.
