Answer 1

Answer: Electric Power and Other Industries

Magnets offer many benefits to the industrial world. Magnets in electric generators turn mechanical energy into electricity, while some motors use magnets to convert electricity back into mechanical work. In recycling, electrically-powered magnets in cranes grab and move large pieces of metal, some weighing thousands of pounds. Mines use magnetic sorting machines to separate useful metallic ores from crushed rock. In food processing, magnets remove small metal bits from grains and other food. Farmers use magnets to catch pieces of metal that cows eat out in the field. The cow swallows the magnet with its food; as it moves through the animal’s digestive system it traps metal fragments.

In the Home

Though it may not be obvious, most homes contain many magnets. Refrigerator magnets hold papers, bottle openers and other small items to the metal refrigerator door. A pocket compass uses a magnetic needle to show which way is north. The dark magnetic strip on the backside of a credit card stores data in much the same way as a computer’s hard drive does. Vacuum cleaners, blenders and washing machines all have electric motors that work by magnetic principles. You’ll find magnets in phones, door bells, shower curtain weights and children's toys.

Other Devices That Use Magnets

People continue to find new and interesting applications for magnets. Magnetic Resonance Imaging (MRI) scans use magnets to align hydrogen atoms in the body, which helps to produce detailed three dimensional images of areas in a patient's body. Magnets are used by researchers to bring particles up to relativistic speeds. Magnets are used in a similar way on a large scale to suspend and accelerate maglev trains, which are capable of achieving incredible speeds.
