subject: Rare Earth Magnets - Super Strong Magnets Of The Future [print this page] Rare earth magnets, which were developed in the last half of the 20th century, are considered permanent in nature and extremely strong. These magnets are used for industrial needs such as electro dynamic bearings and in the motors of many cordless drills as a component of the motor, commercially in audio video equipment and even in the making of modern science type toys and puzzles.
Many sphere shaped puzzle toys are available and these are perfect for older children. Smooth and unique in shape, children are drawn to them. Due to the extreme magnetic abilities, they pose a high risk for small children who may swallow them, which has caused serious intestinal conditions. Some larger magnets have been known to be so strong as to cause injury or damage, to both humans and furnishings.
In the business sense, they have been used for memo holders, jigs, and more. Consumers find many uses both in the home and around the garage. They are quite affordable and easily purchased either online or through a local retailer. Sold in the bags of ten or more, they are durable, functional and very affordable. Commercial uses of rare earth magnets include audio speakers, computer hard drives, fishing reels and bicycle dynamos. For school science projects, nothing will be better.
The two types of permanent magnets are neodymium and samarium-cobalt. Neodymium is by far the more affordable and also the strongest, which was invented in the early 1980s. Samarium cobalt is usually weaker in strength but also very expensive. Some of the current uses for super magnets include being used in trains, roller coasters and even in the research and development of levitation devices. The military has been experimenting and utilizing magnetic technology for decades.
The only draws back to these magnets is the tendency to break and as such are usually coated for protection. Large or small, magnets are popular for numerous reasons and can be purchased quite easily. Many times stronger than normal magnets, these super magnets are perfectly suited for numerous tasks both at work and at leisure.
The price will be dictated by the amount of magnets purchased. Many sizes are available from small to very large. Bulk purchases will be the most economical, most business owners know that by buying in large amounts a better price is arranged.
Rare earth magnets are unusual but not very rare, they are about as common as tin or lead. Their fantastic strength is what makes them so desirable both with consumers and with business owners. The future of these magnets may have yet to be fully realized, however, ongoing research is sure to uncover many more uses for these handy, hard working magnetic helpers.
