Magnets have been in use for a very long time and they now take up a large chunk of every

industry since they are used in most of the common and important technological devices that are

found in households and industries alike.

The magnets that are used most are popularly known as earth magnets. They are very much like

any other permanent magnet but the metal they are made from is what sets them apart. Rare earth

magnets are made from metals that are ferromagnetic. Ferromagnetic metals are those that

possess magnetic properties below a certain temperature even without the presence of an external

magnetic field. These metals produce a very strong magnetic force when they are magnetized

and this makes rare earth magnets very powerful.

The strength of a rare earth magnet is said to be so much to the extent that a finger placed

between two magnets can easily be crushed. The magnet force they produce can also be harmful

to the health of young children and babies if they happen to ingest them. It may at times even

lead to death. They should therefore be kept away from children and should be handled carefully.

Most popular

Early magnets were discovered before the 18th

century but rare earth magnets were only

developed later in the 1900s. They then became the magnet of choice for various uses. Of the

two available rare earth magnets, neodymium is the most common. It is found in varying shapes

and sizes.

Rare earth magnets were initially expensive but prices have gone down with time. Regular

consumers can actually be able to buy them for use in their households or any other purpose.

Application

This type of magnets is very common in electromagnetic devices like computer hard drives.

They are also found in refrigerators, metal detectors, cordless items like microphones and even

self-powered flashlights.

Their extra strong magnetic force has pushed along the phasing out of other weaker magnets but

not completely. These magnets are however very brittle and can therefore break very easily if

they fall. They should be handled carefully for this to be avoided.

You can get rare earth magnets according to your specific needs. If you need them in varying

strengths, different sizes and shapes they will be customized to meet your exact specifications. A

licensed manufacturer would give you good quality magnets since the sale of such magnets is

controlled. Where you are not certain what design would work best for your project, the

manufacturer would be able to help you design your own customized magnets for your project.

Any magnetic data storage devices like computers and credit cards should be kept away from

these magnets at all costs because they could easily be ruined. Such storage devices have their

data stored in magnetic patterns. When a magnet passes over them, especially a strong one, the

pattern gets scrambled and the data gets erased. Such strong magnets require very little time to

erase data on such devices so be very careful around them.
