According to history, there is one very popular legend that tries to explain how magnets were discovered. According to this legend, the discovery was made over 4000 years ago by Magnes, an elderly man who has herding his sheep. He was at a place called Magnesia that is found in the Northern part of Greece. As he was herding, he happened to stand on a black rock that made his shoe nails and walking stick get stuck to the black rock. His walking stick had a metallic tip. He started digging around and found lodestones. The immense black rock was named magnetite after him and the Magnesia place he found it. Disc Magnets.
There are some health benefits that are tied to the use of magnets. According to history, Cleopatra used magnets to maintain her beauty by sleeping with them. In the 2500 BC era, people commonly used magnetite on their skin to keep it looking young and supple. In the world today, the Chinese have been using them to stimulate various pressure areas through reflexology in order to relief pain and aches in the human body. To aid in arthritis, people use magnetic bracelets.
This is how magnets work. There are different types of metals that have microscopic properties of a magnet. Each of these metals contains billions of atoms that clump up forming domains. Domains are groups of atoms that face the same direction. Different domains tend to act in the same manner forming a bar magnet. In normal situations the tiny domains face different sides thus they tend to cancel each other out, neutralizing the magnetic effect of the metal. In order to have the domains face the same direction, one can pass an electric current through the metal forcing the domains to face a similar direction. A natural magnet is then created.
Magnets are used as valuable resources in various ways to help reduce pollution. Many of the electrical motors that are produced in the market have magnets. They are also being used to develop trains in the continent of Asia as well as in the United States. These trains are projected to move at a high speed
The future of magnets lies in the emerging technology. There are so many ways magnets can be used in computers. Currently they are used in hard drives allowing them to spin very fast and to erase or write digital memory. Disc magnets are also used to create blank spots in discs. In future, magnets will be used for very many technological purposes. They will be used in hovercrafts as adhesives among other purposes. They are the perfect resource since they can be renewed and they do not create waste or increase pollution.
Magnets have become an underlying necessity without you noticing it; they are so powerful that even in just a small piece would already suffice in storing much memory, and they are so useful that even your laptop, media player, and just even your simple calculator have them as an essential part. And guess what? They are the culprit behind how these gadgets go smaller and smaller from time to time. But just about any other thing that offers you genuine service and caters to all your needs with sheer limitations, these magnets have also the downside of being dangerous.
Defining Neodymium Magnets
Though these neodymium disc magnets have been labeled as one of the rare earth elements, they seem to be plentiful in many ways than one. These magnets are actually abundant in the Earth’s crust only that they are in powder form making it hard for man to mine large quantities as they also are unevenly spread all over place. There is actually a variation in magnets: variation that is usually brought about by their differences in several properties. Three properties distinguish neodymium magnets from the rest: their remanence, coercivity, and value of energy products. Remanence refers to strength of the magnetic field exuded by a magnet. Coercivity is simply how a magnet resists demagnetism or the degeneration of its poles. And the value of energy products refers to the quantity of magnetic energy being emitted by a magnet. Neodymium magnets have the highest concentration properties within them separating them from the other types.
Value And Usefulness
Since these neodymium magnets offer great magnetic strength even in small quantities, you are sure to find them in almost any gadget, machine, and equipment you have in your home. Cordless tools, DIY drills, and other motor-driven appliances have become a commonplace for these magnets. Hard disks, computers, and laptops also utilize this type of magnet to maintain their functionality.
Trouble
Magnets are also regarded as dangerous especially to kids. Since most toys out in the market today make use of magnets, even in just the minutest form, to bring about apparent attraction to how these toys could function, children have become exposed to the danger that these magnets offer. When a child swallows a single piece of magnet, it wouldn’t sound that alarming. But when a child swallows two, then, an impending trouble is just underneath. As these magnets have poles in them, any attraction between the two could cause an obstruction leading the case to a serious level. Disc Magnets.
Magnets are one of the world’s fascinating gifts; their usefulness in almost any industry, field, and work is more than enough for you to consider them as such. You can find them in almost any motor-driven appliance you have at home, inside your laptops, and even in some of your toys. But be careful, these magnets remain to have trouble in between their poles.
