Facts On Rare Earth Magnets

Rare earth magnets came into existence in the last half of the twentieth century. They are permanent magnets considered to be very strong in nature. These magnets are used in electrodynamic bearings in industries, in the motors of motorized cordless drills, audiovisual equipment and in the manufacture of state of the art toys and puzzles.

Spherical puzzle toys are available in the market and are meant for older kids because the permanent magnets pose  serious a health risk to younger children when ingested. Children may swallow the pieces because they are spherical and very attractive. The magnets which are extremely powerful can cause serious intestinal complications when ingested. Some larger rare earth magnets are so strong that they are known to cause serious damage to both furnishings and humans


These magnets have been in use in workplaces as  jigs, memo holders and in various other uses. They have also been in use in homes and garages. They can be bought online or from a local retailer. Rare earth magnets  are used commercially in audiovisual devices, fishing reels, computer hard drives and bicycle dynamos. They are also used in schools for science and engineering projects. They are sold in bags mostly of tens or more magnets. This group of permanent magnets are very durable, affordable and functional. Their super magnet characteristics makes these permanent magnets desirable for many industrial applications.





There are two types of rare earth magnets, they are Samarium-cobalt and Neodymium. The strongest and cheapest of the two is Neodymium. Neodymium was developed in the early 1980's. Though weaker in strength, Samarium-cobalt is very expensive. Samarium-cobalt magnets are used in roller coaster and trains. They are also used in research involving levitation devices. The military has been using and running experiments on magnetic technology for many years.

The only major disadvantage with rare earth magnets is that they are very brittle and break very easily. To counter this property, the magnets are coated with a reinforcement for protection. These magnets come in various sizes and can be purchased easily. These super magnets are well suited for both leisure, commercial and industrial purposes. The price of the magnets vary with the quantity purchased. Bulk purchases are very cost effective as a better price can be negotiated and agreed upon by both parties.


Despite their name, rare earth magnets are not as rare as many may tend to think, they are as common as Lead and Tin. their super strength make this type of magnet very popular with both business owners and consumers. The full potential of this type of magnet is yet to be exploited but ongoing research are showing positive results and is sure to reveal more uses for these super magnets.
