Did you ever play with magnets? Did you see how they can stick together, or push away from each other? This fascinating phenomenon is known as magnetic attraction and repulsion. Playing with magnets is like magic! Magnets have a unique pull to either pull them together or push them apart. It is an invisible force, one that you can catch only by feel, when you attempt to place two magnets in proximity to one another.
Magnets have a natural power called magnetism, which is pretty cool! Every magnet has two ends, or poles, as we call them. These two poles are called North and South. They are attracted when you bring one pole near the other pole of a different magnet. That means they come together. However, if you attempt to bring two similar poles together, for example, North and North or South and South, they would repulse each other. This is called repulsion. But magnets can take all shapes and forms. Some are small and can hold a piece of paper on your fridge, while others are far bigger and are used in large machines and equipment.
Magnets produce a nonvisible region added to its environment known as a magnetic field. This field is invisible to you, but is present! The magnetic field is strongest near the pole of the magnet (therefore the force is strongest there). The farther away from the poles you are, the less prominent the magnetic field is. It’s the magnetic counterpart, such that when you bring two magnets close to each other, their magnetic fields can interact. This interaction makes them either attract or repel with each other according to the facing places of poles from each of the magnetic fields. Its like tug of war pulling in or pushing out!
Magnets are in a lot of everyday things that you use all the time. Ever wonder how speakers work? A magnet inside the speaker creates the sounds that come out of your music player or TV. Moved by a magnet, a component, called a cone, is whirled back and forth, creating the sound waves that we hear.
You may also see magnets on your fridge. These magnets are highly significant because they assist in closing/releasing the fridge door so tightly. They achieve this by adhering to a metal plate residing on the fridge. In this way, when you open the fridge, it doesn’t go wide open and whatever is in stays safe. Some cars actually use magnets to assist them with running! String of electric motor: There are magnets inside the electric motor of a car that spins and rotates wheels so the car would move smoothly.
It was a long, long time ago, but the ancient Greeks knew about the unique power of magnets. They discovered magnets, but didn’t truly grasp how they worked. Scientists spent a long time and a lot of effort to uncover how electricity and magnetism are related. They discovered how charges in motion produce a magnetic field. This new mechanism helped explain how magnets function, and led to many novel applications of them.
Magnets are used in many aspects of our life today. So, for instance, in medicine, you have magnets in MRI machines that take pictures of inside your body. This allows doctors to look inside you without performing an operation. Trains that run without touching the ground use magnets, too. They are guided by magnetic levitation and glide effortlessly along a rail. Many of the things we use every day would not work the way they do if it weren’t for magnets.
