One of the most recent discoveries which is very useful in various industries is neodymium magnets. These rare earth magnets were discovered a century ago. However, some industries in the early 1920’s successfully isolated these magnets and then use them as primary materials in manufacturing all sorts of products. Today, they are used by manufacturing, electronic, and health industries in order to create all kinds of consumer products and hospital equipments. For example, neodymium magnets are used in MRI machines, computers, security systems, and children’s toys. There are various shapes of neodymium magnets such as rectangular, spherical, round, square, disc, and horseshoe which are either sintered or bonded.
Neodymium magnets are now widely used especially in the health industry. People use it for its therapeutic properties but in spite of its popularity, there are still controversies surrounding this material. On the other hand, there are many athletes who profess that they have been using this because it helps them feel better. They claim that neodymium magnets can alleviate body pains and reduce mental stress. At the same time, it is also believed that it can cure a lot of illnesses. That is why there are many armbands and magnetic bracelets which are now widely sold in the country. These are believed to have therapeutic elements that can promote good health. Although medical experts do not advocate this type of practice, there are still many people who continue to use and promote neodymium magnets.
Online shops are now available if you are interested to purchase neodymium magnets. You can search for websites which offer affordable prices for disc magnets and other shapes of magnets. But be careful in using this magnet since it has been proven that it can also break your bones if it is not used properly. This is due to the fact that there are still many people who do not understand the power of this magnet. In fact, these magnets can easily smash glass walls when they are near each other. Most of all, they can also easily delete data from a mobile phone, computer, and even credit card if it is used carelessly.
Neodymiium magnets are more popular today than alcino magnets. Even if these are relatively smaller in size, they are generally very heavy. Neodymium magnets are also being compared to samarium cobalt magnets as both of these materials are known as rare earth metals.
If you want to buy neodymium magnets, then make sure that they are properly wrapped or covered. These are quite powerful magnets so it is better if you buy only a small amount. You can find all sorts of magnets online whether you are looking for disc magnets or other shapes of neodymium. The important thing to remember is that you need to be very careful. Do not place it within the reach of your kids.
Disc magnets are great tools for fixing something on the wall or any other vertical surface without using any adhesives, nails or hammers. Disc magnets are nothing but a piece of magnet, cut in the shape of a disc, flat on both sides, something like a thick coin. The ways you can use them are literally endless. They can be used for holding portfolios, pictures, art works and souvenirs on walls or doors. It is very common to see the surfaces of refrigerators, cupboards and cabins being decorated by objects held by disc magnets.
There are three types of disc magnets and each one of these has distinctive features and also specific usage. Each type comes with its own pros and cons and hence one needs to be careful while buying one. The most common type of disc magnet is the ceramic disc magnet. This is the cheapest variant available in the market and offers medium strength. Among the ceramic disc magnets, the grade 5 ones are commonplace but stronger ones, up to grade 10 strength are available, especially for technical purposes. Ceramic magnets do not need much maintenance and upkeep, neither do they need fully rust free surfaces to stick on. These disc magnets contain a thin coating of magnetic powder.
Samarium disc magnets are the second type which stand out from the ceramic ones in strength and robustness. While their strength can be found in the range of grade 18 to 33, strengths up to grade 26 are most common. Moreover, they can also withstand high temperatures. For these qualities, samarium magnets are costlier than ceramic ones. One drawback of these magnets is that they are brittle and hence require a little attention, but like their ceramic counterparts, they do not need rust protection as such, and hence are an excellent option for a great many purposes.
The third type of disc magnets in this series, are the strongest ones having strength varying from grade 35 to 55. These are called ‘rare earth’ magnets and are capable of holding very heavy objects. Neodymium magnets, as they are officially called can be so strong, that they can painfully pinch your finger or skin if it comes between two magnets, or one magnet and an iron surface. These are the most powerful commercial magnets and usually come in 35 to 45 grade strength. But all this strength comes for a price. These magnets are brittle, expensive and become defunct in high temperature (above 130oF). They are useful only in a small number of cases.
Disc magnets, are thus capable of doing a myriad of holding jobs. Some can be used for general purposes, while some are application specific. It is best that you choose one with the strength which your application demands
