Earth Magnets: The Best Kept Secret
The first thing anyone should know about earth magnets is that these little things can cause bodily harm. These can crack brittle bones especially when sandwiched between two magnets. If accidentally swallowed, these objects can pinch the stomach lining, causing paralysis or even death. So powerful and reliable are these stones that they have gained a wide range of application. For example, most people are not aware that magnets of this variety are found in today?s computer hard drives, stereo components, phones and many other electronic devices.
For one, these permanent magnets have a superior innate ability to get magnetized in one direction, using the natural formation and action of electrons. So reliable are these simple devices that their power is harnessed to keep bullet trains in motion as well as to control the movement of elevators. Ironically, the average person has no clue just how many of these objects he or she runs into in any given day. While there is growing global concern over the impact of wireless devices on human health, no significant alarm has been raised over the continuing usage of magnetic earth elements.
The Earth itself is a humongous magnetic field, especially when stripped to the core. Any effort to destroy this natural mechanism will not only cause worldwide cataclysms. It can likewise bring about the planet's disintegration into pieces being the source of all the gravitational pull that holds everything together. It was the U.S. military that discovered and successfully isolated the superior power of permanent magnets over the ferrite or the alnico kinds in 1966.
Comparatively, the former has more pulling power over its competition. For example, it has 1.4 as opposed to the ferrite and alnico variety?s 0.5 Tesla, (Tesla or T is the unit of measure used for determining magnetic power). The word rare has often been associated with the words earth magnets, creating the misconception that these metals are rare, indeed. On the contrary, these are about as common as aluminum or tin. Fabricated, they are thus classified as alloys, the word used to describe the metallurgical combination of molten substances to artificially create a material of desired durability for industrial use. For example, bronze is a combination of copper and tin, while brass is a mixed copper and zinc.
Earth magnets, on the other hand, are a neodymium, iron, and boron combo. Another hybrid is that of samarium and cobalt with superior advantages of its own, although this type is relatively less marketed than the neodymium variety due to production costs. Because of such widespread application, manufacturers sell these magnetic rods, cubes, cones and spheres in differing quantities over the counter. Some even offer specials such as an assorted pack of 80 for as low as $25. Because there has not been any study or studies claiming any health hazard for the application of these magnetic objects in modern society, their unabashed usage is likely to persist. However, the public should recognize some dangers, such as being pinned between two permanent magnets, or the threat of babies or young children accidentally swallowing these objects. Nevertheless, take away all these, and elevators, trains and even roller coasters for that matter, could grind to a halt.
