Neodymium Magnets Provide Major Power For Modern Devices

In addition to being a popular fascination for folks of all ages, magnets serve many useful daily functions. Magnets are essential components of many modern electrical and mechanical devices. Without them, major appliances, industrial machinery, and medical equipment would not exist or fatally malfunction. Neodymium Magnet.

The three main strong magnet classifications are electromagnets, magnets of the permanent type, and magnets that are temporary. As the term suggests, permanent magnets retain their magnetic force perpetually. Most modern refrigerators and many electronics products such as PCs, certain appliances, and toys contain permanent magnets.


Magnets of the temporary variety have a metallic construction and will adhere to other magnets. Standing alone, however, they have no magnetic pull. Common paper clips and nails fall into this category of magnets. Electromagnets require electrical contact to become magnetized.

The two most powerful magnets of the permanent type are neodymium and samarium-cobalt magnets. Both types are made of various metals and are available in a variety of shapes and dimensions. Such magnets may be bought via the internet or at upscale hardware retailers. Some of these types of magnets have a protective outer layer to help maintain and lengthen magnetic half-life. Although samarium-cobalt and neodymium magnets are often denoted as “rare earth” magnets, their construction includes no rare substances at all.

Neodymium magnets serve especially useful functions in contemporary society. In addition to common major appliances, they are used extensively in medical magnetic therapy applications. Magnetic therapy is thought to relieve pain and permanently cure some illnesses. Although controversial and debunked by many medical practitioners, many are convinced of the therapeutic value of magnets.


Special precautions should be observed in the use and storage of very powerful magnets. Mishandling even the smallest rare earth magnets can result in severe injury or death. Safe storage is also essential. These powerful magnets must never be allowed near hard disks, computers, credit cards, or USB drives. Complete erasure of all data stored thereon is the probable consequence of such careless close proximity. Likewise, pacemakers can malfunction very easily and rapidly if the wearer comes too close to a rare earth magnet.

Magnets are a mainstay of contemporary life. Many devices we take for granted would be impossible to operate without temporary, permanent, or electro magnets. Very strong magnets such as neodymium types are extreme fascinations; further practical uses for them are likely to be devised in the near future.


Extreme caution is always highly advised in the use and handling of strong magnets, however. They must be kept at sufficiently far distances from electronics products. They must also used with utmost care. Never allow children to play with them. Anyone thinking about buying a strong magnet who wants further information can find it at a local hardware outlet or online.
