Chemically, they have a tetragonal crystalline body structure. Originally priced heavily, they have recently become affordable for daily use purposes and are a new product in the market.
The magnets were developed for the first time in the year 1982 by General Motors and Sumitomo Special Metals. The strength is greater compared to the magnets made of ferrite or alnico. They have slowly and gradually replaced other varieties of magnet used for various applications.
The strength of the magnetic field produced by them can measure up to around 1.5 teslas.
Rare Earth Neodymium magnets are the strongest type of permanent magnets made from an alloy comprising of neodymium (Ne), iron (Fe) and boron (B) in varied proportions. They are often referred to as “NdFeB” magnets because of their constituents.
Different Properties of Rare Earth Neodymium magnets
The structure of Rare Earth Neodymium magnets is designed specifically to have a high uniaxial magneto-crystalline anisotropy.
This allows the specific compound to have a high coercivity value. With a magnetic field value of 1.5T, they even have a relatively high value of saturation magnetization. The maximum energy being directly proportional to the saturation magnetization, it has the capacity for the storage of magnetic energy in large amount.
The properties of the Rare Earth Neodymium magnets largely depend upon the constituent elements and the manufacturing technique. The crystalline structure gives them a high value of magnetic anisotropy.
It implies that a small crystal of the material can be magnetized easily in a particular direction but it will resist doing the same in the other direction.
Various Applications of Rare Earth Neodymium magnets
Rare Earth Neodymium magnets are used almost everywhere in today’s world. The great strength of the magnet facilitates their usage for both large and small magnets. It is used extensively in preparing toys for children and adults.
They are used in welding clamps to hold two or more pieces of metal together.
They have similar applications in drilling and machining. They find applications in oil pans and oil filters to filter the metal chips out of the oil.
They are even used as stud finders to locate hidden nails in the walls and flooring. They are used abundantly in the preparation of various computer hard drives, dynamos of bicycles, audio speakers and headphones, fishing reel brakes and in making permanent magnet motors in cordless tools.
These magnets play a pivotal role in generating electricity in shaking motion in the construction of self powered flashlights.

SEO
What is SEO?
SEO stands for search engine optimization.SEO is one of the most efficient things one can do for getting his website listed in the top search results of the major search engines. Getting listed higher in search engines can send more traffic towards your website.
But SEO is not that simple as it sounds. You have to optimize your website and the contents in such a way to rank it higher in the search results.
You must have observed that when user search for something in the search engines, he clicks the links from the top search results and the rest of the results are simply ignored.
Thus, there is heavy competition among different websites to be ranked higher in the search results of major search engines.
In simple words, SEO is marketing through an understanding of how search engines work and the algorithms they use.
Why SEO is important:
SEO is becoming one of the fastest growing marketing strategies in the online world. Internet market is growing daily exponentially and the common people are made to choose the online services due to its comfortable and simple attributes.
In this online market, every website is trying to attract more and more customers towards it. Search engines play a very important role in prioritizing different websites in terms of their products and services which depends on SEO of the website.
Thus, SEO is a very important tool for online marketing :) !
Traditional marketing methods like advertisements in newspapers or magazines are becoming limited due to various factors. One of the most important reasons is the limitation of the exposure of the advertisement due to readership, popularity, business markets and so on.
However, cost is also a very crucial factor as newspaper and magazine advertisements costs a lot if you are planning for a continual marketing. SEO may be a slow process but if optimized in a proper and efficient way, SEO could give long term benefits to the website.
Implementing SEO:
SEO has become a necessity nowadays for better online marketing. But, implementing SEO in your website and its contents is not that easy. First of all you need to choose keywords according to your target groups for an efficient SEO.
This is a very difficult as you need to do some keyword research about the target words which you are planning. You have to insert 1-3 keywords per page for SEO.
A large number of keywords in a single page could also affect the optimization process. These keywords have to be used in strategic locations in the website which includes Title tag, Keyword tag, description tag and header tags.
Continuous implementation of SEO could definitely help your website in getting listed higher among the search results.

Magnets
A magnet is usually a substance or an item which can generate a magnetic field around its surroundings.
They can attract various ferromagnetic substances like the iron. They also have a property of repelling when they are kept with other magnets.
There are different varieties of magnets in different shapes and sizes available for both used in home and industries.
What are the various types of magnets available?
There are three main types of magnets which are temporary magnets, permanent magnets and electromagnets. Permanent magnets are used in everyday life like that in the refrigerator. They are generated when a magnetic substance has a prolong magnetic field. They retain the degree of magnetism.
Temporary magnets are those magnets which acts like a permanent magnet only when they are place inside a strong field of magnetism. But they lose their magnetism as soon as the field disappears. Soft iron nails and paperclips are the common examples of the temporary magnets.
Electromagnets are those magnets which contains an iron core usually surrounded by coils of wire. When current flows through the wire, it acts as a permanent magnet. The polarity and the strength of a magnet generated by the electromagnet can be adjusted by varying the strength of the current which flows through the wire.
It is also depended on the alteration of the direction of the flow of the current.
What are the uses of the magnets?
There are different applications of magnets in various fields. They are used in the common items used at home to complicated devices in industry. They are very important in everybody’s life and are pretty useful.
They are used widely in cassettes, hard disk and floppy disks. In industries they are used as separators, pullers, sweepers, welding and conveyors. ATM cards, debit cards and credits also uses magnet which is used in the magnetic strips. This magnetic strip helps in encoding the details about a particular individual about his bank details and account.
They are also widely used in microphones and speakers. In the health sector, magnets are used in MRI where various different organs of the human body is scanned for surgical reasons. They are used in many jewelry objects like earrings, bracelets, necklaces and pendants.
Magnets are also used extensively in many magnetic therapy equipments which include magnetic massager, magnetic waist belts, magnetic mattresses, knee magnets and many others. Generators and electronic motors widely use the magnet.
