Magnets do more than hang things on your refrigerator. In fact, the list of everyday uses of magnets is a seemingly endless one. |
Perhaps most importantly, there are many medical uses of magnets. Doctors have debated for many years whether or not the human body is sensitive to magnets, and if they're effective in treatment for various diseases and other ailments. There's no denying the therapeutic benefits of magnets in medicine, though, and they have been administered in this way for several years. For example, a high-energy magnet can create a magnetic field strong enough to penetrate deep into the body. This feels extremely therapeutic to the patient. Other forms of magnetic medical care include magneto-acupuncture, magnetic bandages, and specialized magnets for use during brain surgery.
Most common uses of magnets take place in your own home, though. For one, magnets have revolutionized the efficiency of the appliances you use every day. Refrigerator and freezer doors would swing open freely and be unable to keep your food properly stored without a magnetic strip to keep those doors securely closed. Microwaves rely on magnets to channel their energy in the right direction and heat your food. Even sinks rely on an embedded magnet or two to reduce the amount of limestone build-up in your basin and pipes.
Magnets also find their way into many electronics. All laptops house a magnet in their hard drives, while most models also have a magnetic clasp at the top of the screen that signals to the computer when it's opened or closed. Vacuums use magnets so that they have stronger suction and work more efficiently. Speakers rely on magnets to react with a copper wire inside of them; this reaction makes sound. Older models of televisions and computers house magnets to sharpen their pictures, although that technology is being phased out. This is because their screens might be damaged or destroyed if they're placed in close proximity to a strong magnetic force.
Even your home security system, telephone, duvet cover, treadmill, bathroom scale, washing machines, and electric motors count magnets as part of their makeup. Perhaps it would be easier to make a list of everyday items that don't rely on magnets to function more efficiently, or function at all.
