A permanent magnet creates a continuous magnetic field. These are often made from the same materials that are strongly drawn by magnets, such as iron, nickel, lodestones and certain rare earth elements. These magnets are used for many purposes. Simple refrigerator magnets are one mundane use of permanent magnets. Industry also uses magnets in a number of crucial areas. Some people even claim that the proper arrangement of these materials in a permanent magnets motor will create a machine that emits free energy that does not require the input of any additional energy.
Many devices that are now common depend on the use of magnets. Computer hard drives use magnetic coatings to record immense amounts of data. Credit cards and ATM cards all bear a magnetic strip on the back which millions of people use to make everyday purchases. Speakers, microphones and other items used in entertainment also use magnets to convert electricity into mechanical energy. Many people have undergone magnetic resonance imaging, or an MRI, in a hospital setting. This is a highly useful and beneficial procedure which depends on the use of magnetic power.
There are claims of things much more incredible regarding magnets. Entranced, as many are, by the incredible power of magnets to both attract and repel objects, some researchers insist that the right arrangement of magnets can produce a machine which creates free energy. In other words, they claim that a permanent magnets motor can take an initial input of energy and continue creating electricity without any more input. This claim, if true, would mean that energy in the future would come at no cost. Furthermore, use of this energy would have a negligible impact on the world. Such a motor would revolutionize the world in terms of energy and politics.
Aside from such grandiose usages and claims, there are also many mundane uses for magnetic materials. Everyone is familiar with refrigerator magnets. These apparently simple devices suspend notes and children’s achievements to refrigerators around the world. Like the magnets that appear increasingly often in toys and other simple devices, these magnetic objects were not so easy to create. Making magnets is not as easy as it may appear. They are not mined and then churned out in a factory. The right materials must be found and then combined in just the right way. Furthermore, manufacturers must protect these magnetic alloys from corrosion and other forms of wear.
The use of magnets only seems to increase every year. If some thinkers are correct, then a permanent magnets motor may guarantee even further increase in the use of magnetic materials. At that point, the value of materials used in magnetic alloys will probably soar sky high.
