Many people think of magnets as amusing toys or simply as the objects with which the pin notes to their refrigerator. While magnets do have many simple uses in the world, they are also a crucial part of many industrial applications. They are found, in some form, in most modern technological equipment and in factories around the world. They range in power from the refrigerator magnet to the permanent magnets motors which operate heavy machinery in manufacturing plants.
One way in which magnets have come into the daily lives of most people in modern countries is through their debit cards and credit cards. The magnetic strips on the backs of these items contain coded information about the individual carrying the card and the financial institution which issued them. Many children’s toys also use magnets to create amusing effects. Magnets are used in electric guitars, medicine and a long list of other devices.
One crucial application of magnets occurs in industries that service a wide spectrum of modern activities. Permanent magnets motors are used in many factories. In the last few decades, researchers have developed incredibly powerful permanent magnets from alloys composed primarily of rare earths. These magnets are much more powerful than the kind that you find in toys or on your refrigerator. In fact, they are so strong that they have caused severe injuries when accidents and misbehavior lead people to get their limbs caught between two such devices. These rare earth magnets can break bones even if they are only a few centimeters in diameter.
It is also possible to create magnets temporarily from electricity. An electromagnet is made of coils of wire. This known as a solenoid and you can easily find such devices under the hood of your car. These coils only function as magnets when someone or something runs an electric current through them. This generates a magnetic field which acts just like that of a permanent magnet. In the case of electromagnets, however, you can extinguish the magnetic field by simply cutting the electricity. The power of these magnets can be increased by wrapping them around materials with their own magnetic properties, such as those made from iron.
Magnets become more necessary to the modern way of life with each passing year. Their crucial application in computers is one thing that guarantees their continued use. Additionally, their use in industry in the form of permanent magnets motors is so widespread that consumer societies would be impossible without these devices at the heart of the factories which produce goods. Since researchers have continually sought to create more powerful magnets, you can be sure that magnets even more powerful than those made from rare earth will soon augment industrial capabilities.
