Magnets are objects that have the ability to produce a magnetic field. Both these objects and the field they create is essential to life on the planet. The magnetic field that is produced by our planet, deflects the sun’s solar wind which poses a serious threat to our atmosphere. Basically, everything surrounding magnets is very important in our lives. Even these little objects that create a magnetic field are essential to our survival. Of course, their uses are not just about survival, but also to improve our day to day living.
I believe that every person on this planet should understand just how essential magnets are. Everyone needs to understand their applications, their utilization, and they should never underestimate the power of the magnetic field.

They can be used for basic things like manufacturing toys, for a speaker and even heavy machinery that weighs hundreds of tons. Assuming that you are interested in all the different applications and utilization of these “magical objects” in our lives, make sure to read this article to the end.

Medicine

The level of medicinal technology and knowledge we have is remarkable. Just 200 years ago, we had trouble dealing with the most basic sicknesses such as the flu or even a simple cold. Today, with the medicine we can provide to people, they can live up to hundreds of years and we can even help those with the worst diseases. We have even started transplanting hearts, kidneys, and even brains.
However, most of this will not have been possible without the use of magnets. This is because the most important machine in every hospital around this planet is the MRI scanner which utilizes a magnetic field. By creating that field and using radio waves, doctors can generate detailed images of a person’s insides. Whether it’s the stomach, the lungs, the heart, or the brain, with this scanner they can see everything.
By having an insight into a person’s organs, they can easily come to some kind of conclusion or maybe even a solution for the medical problem the patient is faced with. The best thing about MRI scanners is that they do not pose any kind of threat to one’s health, unlike x-ray machines. Not everyone can handle the radiation poisoning from x-ray machines.
Almost every computer

It is no secret that in today’s world, it is completely normal to have at least one computer at home. Whether it is a PC or laptop, it doesn’t matter. You just need to have something where you can work or browse the Internet.
However, I would say that most people have no idea what is inside of the computer and what it is made of. The technology that can be found inside of your computer has been in constant development these past 5 decades. Thanks to scientists around the world, these machines have become smaller, better, and faster. But, without magnets, this wouldn’t have been possible. Without them, we wouldn’t have the ability to store huge amounts of data as we can today.
There are magnetic materials inside of the hard drive which helps store the data inside of the disc. Before we discovered that magnetic fields can help with storing data, one drive could fit only 3.75 MB and it weighed at least a hundred kilograms. It was big, it was heavy and it didn’t even store enough information.
Speakers

Believe it or not, but there is also a use of magnets in every single television, radio, or computer that has its own speakers. It’s pretty interesting to think about how speakers work. Basically, in the speaker, there are usually two objects that are in a magnetic field. One is an electromagnet and the other is a permanent magnet. The permanent one is usually a custom neodymium magnet. According to aomagnet.com, neodymium is usually the best option for creating speakers and other similar products
When the source of the sound sends the information through a current, the electromagnet alters its polar orientation and starts attracting the other object. Once the current alters the polar orientation again, it starts to repulse the other object. This constant alteration of push and pull is what makes the speaker cone produce the sounds that we hear.
Electric motors

Fortunately, these last several years we have made a lot of progress in electric vehicles. The use of electric motors, we can completely replace fossil fuel engines. But, how do these electric motors work?
Well, with enough wire coil and a strong enough magnet, you can basically do anything. The combination of these two is what turns mechanical energy into electricity. That is basically how every electrical motor works. You can easily check out Tesla, Porsche, Audi, and all of those companies that have released electric vehicles in these last couple of years to find out exactly how their electrical motors work.
Home use

Even objects and items that you use on an everyday basis probably have some kind of magnetic field in them. For example, the electric motor inside of your dishwashing machine or clothes washing machine. Your vacuum cleaner, your blender, and maybe even inside of your phone.
Those little things that you use to stick notes, your children’s drawings, or your favorite bottle opener to the refrigerator door, is also a magnet. Even the refrigerator itself has one to keep the door always closed.
It seems like everywhere you turn there is some kind of use for magnets and that without them, we probably will have never reached this level of technology that we have today. This is why it is important to understand the technology that we use every day.
