Magnets are Everywhere!

magnets are everywhere

Magnets are something you don’t spend a lot of time thinking about, but they are part of our every day events. Beyond those of us with magnets plastering our fridge holding up all our things to be remembered, magnets make tasks in our daily lives simpler. If you take the time to think about it, you realize that magnets are everywhere!

Let’s start with those magnets on your fridge. Maybe you’re a minimalist and prefer not to clutter your fridge with anything. Perhaps your fridge is your command center, so it is where you put your calendars, invitations and your magnetic dry erase meal plan board. You can also buy magnetic picture sleeves and create a collage of your friends and loved ones.

Many folks like to collect magnets from places they’ve traveled as souvenirs. Additionally, promotional magnets are one of the most common giveaways from companies and various organizations. You may have a magnet clip for holding files, or an informative magnet that tells you who to call in a power outage, or a magnetic reminder of the proper conversion of tablespoons to cups.

Beyond “fridge” decor, you can find magnets in many other places, like your car – magnetic bumper stickers are now preferred over stickers as they are easier to remove. If you have a child who is a student using a locker, there are many different types of magnetic organization and decoration supplies to use. Magnetic hooks and curtain rods can be use on metal doors. Magnets are also commonly used on a variety of cupboards and doors to provide a secure closure. Even newer mailboxes are switching over to a magnetic closure.

Magnets are also used in many scientific applications. We rely on magnets in electric generators to convert mechanical energy into electricity. Interestingly, once we get that current into our homes, we have motors that utilize magnets to convert electricity back into mechanical work. They are especially important for the electronic devices we have come to rely upon. Below is a short list of just some of the many household electronics that use magnets:

  • Ice dispenser
  • The rotating tray in a microwave
  • Fans
  • Hair dryers
  • Aquarium pumps
  • Garage door opener
  • Blenders

Magnets have also revolutionized the medical field, particularly with imaging. Magnetic Resonance Imaging (MRI) machines use powerful magnetic fields and allow us to see inside the body by generating radio signals. Magnets are also used in cancer treatment.  Doctors inject magnetic fluids into cancerous areas and use a strong magnet to create heat in the body. By doing this, they can target the cancer cells without damaging patients’ healthy tissues.

Any technological device that has a hard drive uses magnets. Your computer relies on magnets to spin the motor of the hard drive. Likewise, any speaker you use to listen to your favorite tunes was built utilizing some form of magnetism between a coiled wire and a permanent magnet.

Nowadays, everywhere you go, you see people wearing headphones as they make their way to work, home or to leisure activities. One of the most mind-bending facts of all is that without magnets, we would not have the internet that we use for just about everything! The internet relies on a vast network of hard drives, and as previously mentioned, hard drives employ magnets. We need these hard drives to store the vast array of information that is available online. You are reading this article because of a web of hard drives that hold the information online together.

Our modern world is made possible by magnets. Without us even giving them much thought, magnets are quietly making things happen for us all day long.
