Neodyimium Offers A Low Cost Yet Effective Alternative To Traditional Permanent Magnets

Neodymium rare earth magnets are known as the strongest magnets in the world, although they are a manufactured product, rather than a naturally occurring ore. Initially intended to be an economical replacement for more expensive permanent magnets, neodymium magnets have become common in a wide range of applications, from generators to cabinet closures. A more recent application, however, is in the field of magnetic therapy, as the intense magnetic properties are often credited with reducing pain and improving overall well being.


Neodymium rare earth magnets are a relatively new invention, with the discovery taking place in 1982. The term rare earth is misleading, however, as the material is actually an alloy consisting of neodymium, iron, and boron, all of which are both common and abundant. It is the abundance of the alloy materials combined with its high resistance to demagnetization that has made neodymium magnets an economical alternative to traditionally expensive permanent magnets and has further opened the door for use in a wide range of both industrial and commercial applications.


The use of neodymium rare earth magnets first became popular for use in generators. The basic design of generators includes an internal coil that is placed inside a magnet field, with the generation of electricity resulting when the coil is spun inside the field. Neodymium magnets have become especially preferred because of their powerful magnetic strength, which enables smaller magnets to be used in place of the typically large permanent magnets that had been commonly used in generators. The lifespan of neodymium magnets adds a further benefit, as the magnetic properties generally last around 10 years. However, the lifespan can be shortened considerably if magnets come into contact with water.




The ability to create small but powerful neodymium rare earth magnets also enables them to be used virtually anywhere a magnet is needed. This includes cabinet and purse closures, as well as in latches for jewelry and watches. They have even become popular in the automotive industry, as neodymium magnets can effectively remove metal shavings from the oil reserve by simply being placed in the oil pan.


Neodymium rare earth magnets have more recently gained popularity for use in magnetic healing therapies. Magnetic therapy in itself centers of the use of magnets to reduce pain and encourage the natural healing process of body, with the effectiveness often depending on the strength of the magnets. The strength of neodymium magnets have made them ideal for this form of therapy, both in spa treatments and through a number of products that can be purchased over the counter. Magnetic rings and bracelets are the most common therapy products, although insoles, bedding, and joint supports are becoming increasingly available. Pet products are also being made with the inclusion of neodymium rare earth magnets, with the most common items being sleeping pads and pet beds.


Neodymium rare earth magnets were initially developed to be an economical alternative to other, more costly types of permanent magnets, although the powerful strength and long life of the magnetic properties has led them to become popular for a wide range of other applications. Cabinet closures, jewelry latches, and automotive purposes have become common uses of neodymium magnets, with magnet healing therapy being a more modern application. The ability to create small magnets that maintain strong magnetic properties have added to the versatility of neodymium rare earth magnets, which had made them one of the best low-cost, effective, and extremely practical modern inventions to date.

Finding A High Quality Neodymium Magnets.

If you are an inventor or manufacturer in need of high-quality neodymium magnets, there are a number of sources offering the strongest rare-earth permanent magnet for less.  When you are developing an invention or producing the product in bulk, you must find a distributor that sells only fully licensed products to avoid future patenting problem or legal nuisances.  While there are a number of neodymium and strong metal manufacturers on the Internet, not all magnets are created equally in quality, size, or process.  Finding a distributor with a widespread selection that will fit the needs of your project will be an invaluable asset the overall quality of your product and productivity of your sales.  Do no invest in sub-par rare-earth magnets and do your research for various rates and styles of this strong metal.


Browse various inventories.  An online distributor with a variety of different strong neodymium magnets coming in various different shapes including cylinders, discs, cubes, blocks, rings, triangles, spheres and stars.  Another popular type, the neodymium-mounting magnet, should be plated in nickel and steel for optimal performance and strength with fastening features for any type of project.  With various shaped mounting magnets with and without hooks, you will have incredibly handy tools for your garage, shop, invention or even your residential refrigerator.  





Neodymium magnet pricing will differ significantly amongst the distributor or wholesaler.  While browsing inventories of various reputable online companies, be sure to check the rates of the shape and size you prefer per unit.  Most companies will offer a per unit price that will decrease as the quantity you need increased.  If you see a future need for these magnets consider buying in bulk and saving money over time.  Some companies will also offer surplus magnets that are manufactured in error and never sent to a customer.  While these are brand new and in mint condition, they are significantly discounted and could be the perfect choice for buyers on a budget.


If you are preparing for a project and you are unsure of the shapes and sizes of neodymium magnet you will need, many companies sell sample packages that include a number of different types of strong magnets at a discounted price.  While there may be only one or two of each of these magnets in the package, it will give you the tools you need to determine which shape and size is fitting for your purpose.


As with any purchase, do your research and find a reputable dealer that offers fully licensed products for your invention endeavor for less.  With the convenience of the Internet, and the gathering of a number of different styles of neodymium magnets in one environment, it has never been easier to invest in a quality product.
