Why There Is Magnetic Ball Rubik Cube

Believe that people must play Rubik's cube, which is a great test of people's endurance and mental ability. Many people enjoy playing rubik's cube for all their life, taking it as a kind of perfect enjoyment. In the historical development of the Rubik's cube, we are sure not to ignore a kind of magnetic toys, the magnetic ball Rubik's cube.

The main material of magnetic ball rubik's cube is the rare earth magnet, and it consists of two hundred and sixteen magnetic ball of same size. Each of the magnetic balls has function to indicate the direction. However, the magnetic balls are firmly absorbed together, which allows people to freely make random shape transformation, such as common outside the square, rectangle, and a variety of irregular polygon. In addition, when you do not want to play, they could be restored to the original rubik's cube.

In addition, creative magnetic ball cube can even become various magnetic jewelry, such as necklaces, bracelets, etc. And this can reflect people's personalities. After all, the jewelry of people is usually made of gold, platinum and other precious metals, so the magnetic jewelry is very novel. Visibly, magnetic ball rubik's cube is a very interesting product, which can exercise the people’s creative ability.

The Magnetic Rod Used In Food Industry

Generally the magnetic rod is mainly used to filter various small powder or liquid, and it can take away the iron and magnetic impurities in liquids. The nature of this determines that it can be widely used in the food industry, where the products require fine processing and refinement.

A good quality rod can reach a state that the magnetic induction lines distribute averagely in the space, and inductive power with the maximum magnetic averagely distributes throughout the whole magnetic bar. The bar is usually placed in the transmission line which can be moved, so the resistance of its magnet surface should be very small, and there must be no impurities harmful to the environment, so as not to contaminate the raw materials.

And its work environment determines that it must have the good properties such as corrosion resistance and high temperature resistance. And when using it in different temperatures, we may need a bar magnet with different magnetic induction ability in order to get different high temperature resistant properties.

 

Oil Filter Magnetic Rod Need Regular Cleaning

The relatively large impurities in mechanical turbine oil can be filtered by the oil-filter screen, but there still remain some impurities smaller than ten microns, which can pass through many layers of the oil strainer into the inner bearing and regulating system, make the bearing wear, also can let the regulating system becomes blocked, which is likely to result in bearing damage, and even make turbine and aircraft accidents. And that is why we need the oil filter magnetic rod.

The oil filter magnetic rod can be used to adsorb tiny ferromagnetic impurities in a steam turbine. As long as keeping the cleaning and maintenance of the oil filter magnetic rod, we can be able to protect the cleanliness of the turbine oil, so as to make the steam turbine and bearings applied on a variety of machines keep running under normal. So the magnetic rod applied in large machines must receive regular cleaning and maintenance so that these machines can be in good working state at any time, and the occurrence of the large accident also can be avoided.

How To Transport Magnets By Air

When transported by air, the magnets need to be entrusted to a special institution (bureau of technical supervision) to do degaussing. The so-called degaussing is not really to eliminate the magnetic performance of the magnet, but to adopt different methods according to different product strength to make the unit packing meet the state requirements for aviation safety transportation.

For some magnets with weak magnetism, we usually use the general iron as the isolation, fix the magnets, pack with the pearl cotton bag, and finally put them into the cartons. Then they can go through the airline Mag&Bag.

As for the strong magnets, we can make them through the airline Mag&Bag by using special package with the effect of the magnetic isolation, and now some magnetic isolation material in the market can achieve this effect. In the packaging process, we usually reassemble the powerful magnet with these magnetic isolation materials, so as to reduce the magnetic strength, and make the strong magnet through the airline Mag&Bag.



                

Three Suggestions On The Application Of NdFeB Magnet

As the permanent magnet with the strongest magnetic force so far, neodymium iron boron magnet has been widely used in energy, transportation, machinery, medical, IT, household appliances industry and other fields. And here are three suggestions on the application of it.

First, the magnetism of neodymium iron boron magnet is very strong, and it is hard but brittle. Therefore, when working in the occasions with the vibration, shock and so on, it may break and even fall off. Hit by strong impact, the magnet debris may even scatter. So there should be the design of necessary protection application to make sure that even though the magnet is broken, the debris will not fly out.

Second, neodymium iron boron magnet should be stored in indoor place that is ventilated and dry. Stored in the acidic, alkaline, hot and humid environment, or in the liquid like organic solvent and water, the magnet is easy to rust, and the powder coating shedding of magnet is easy to demagnetize.

Third, the magnet should work in the clean workplace, so as to avoid the iron filings and other small impurities adsorbed on the surface of the magnet.

Wide Application Of NdFeB Magnets In The Auto Motive Industry

Neodymium iron boron magnets are widely used in medical, industrial and all areas of life activities; especially in the automotive industry field they are widely applied.

With the development of economy, the automobile becomes more and more popular, and now there is an annual output of 59000000 cars in the whole world, while the automobile industry is one of the fields where the neodymium iron boron magnets are applied widely. In each car, generally there has 30 parts using neodymium iron boron magnet, while the use of micro motor number can be as high as 70 in some luxury cars, to complete a variety of control action of the cars. According to the current average using number, we can predict the need of motors will increase from eight hundred million to sixteen hundred million, and each car would need 102 grams of neodymium iron boron magnet.

As the development direction of miniaturization, lightweight and high performance, there will be higher request for the neodymium iron boron magnets used in the car, which will speed up the development of neodymium iron boron magnet, especially the bonded NdFeB permanent magnet.

  

Something About Neodymium Iron Boron Magnet

Application of the magnet is not uncommon in daily life, this paper introduces some knowledge about neodymium iron boron magnets.


First of all, many people may wonder how long the magnetism of neodymium iron boron magnet can last. About this question, neodymium iron boron magnet has high coercive force, so generally, in the natural environment and the general conditions of magnetic field there would not be demagnetization or changes of magnetism. Assuming the environment is appropriate, even after a long time of use, the loss of magnetism will not be great. So in practical application, we often ignore the factor of time effect on the magnetic properties. But if working in harsh environments for a long time, the magnet can appear demagnetization as well.

So, what is the main influence factor of neodymium iron boron magnet’s magnetism? It is the environmental temperature. Since the sintered NdFeB is very sensitive to temperature, the instantaneous maximum temperature and sustained maximum temperature of environment may lead to different degrees of magnet demagnetization, including reversible and irreversible demagnetization, and recoverable and unrecoverable demagnetization.
