Rare Earth Magnets For All Your Magnet Needs

At its highest point in our history, throughout the world including in the United States is the advancement of technology.  Although it would not be fair to say that any one product is responsible for most of the technology that the world has been able to create.  However, it would be fair to say that an essential piece of most modern day electronics is some type of magnet.  The use of ferrite magnets were originally the most commonplace, however over the last year or so, becoming increasingly popular is what is known as rare earth magnets.  These have become popular to many manufacturers of electronics in part for their increased efficiency and available at a reduced cost.  Samarium-Cobalt and Neodymium are the two main types of rare earth magnets. Neodymium Rare Earth Magnets.

In the 1970s came the first conception developing rare metals of the earth into magnets. Having a great deal more power than a standard magnet, these rare earth magnets have and exhibit all of the typical properties expected from a magnet and are made from the alloy found in rare earth elements.  In their powerful form, they can be cut to smaller sizes, which is what makes them popular with the manufacturers as a cost savings feature.


These powerful magnets have a very wide range of uses and are favored with their low cost for the manufacturers.  In the electronics’ industry their use starts with any device needing a magnet, including electric cars, MRI machines, headphones and speakers and it still does not end as they are replacing more typical magnets in technologies surrounding hard disks and numerous other products.





In the world, one of strongest permanent magnet varieties is the rare earth magnet, Neodymium which produces a force that is stronger compared to the Samarium-Cobalt.  In the early 1980s collaboration between Japanese and American companies discovered this product from an alloy of boron, iron and neodymium in combination.

Stemming from the powerful nature of these magnets, it is entirely possible to suffer injury, although the risk is not very great.  With these small magnets, injury can occur when handling at least two and they quickly snap together, possibly onto the skin.  Additionally, if too much force is placed on the fairly brittle alloy, it can shatter.  As with any electronic devices and standard magnets, these magnets should not have any contact except built into the product by design.  The magnetic force can permanently damage devices like a CRT TV, as well as corrupt or wipe-out the hard drive data. Neodymium Rare Earth Magnets.


In short, it is unquestionable that our advancement in technology includes a large part for these rare earth magnets.  Hidden within electronic equipment, spreading over the world, in an extremely vast range of applications through their power, despite only being developed in the past few decades is the revolution, magnets.
